+# Of course, Automake must honor this variable whenever it calls a

+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a

+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative

+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.

+    Garbage Collector (parallel iversion) for ix86 DG/UX Release R4.20MU07
+
+
+     *READ* the file README.QUICK.
+
+     You need the GCC-3.0.3 rev (DG/UX) compiler to build this tree.
+     This compiler has the new "dgux386" threads package implemented.
+     It also supports the switch "-pthread" needed to link correctly
+     the DG/UX's -lrte -lthread with -lgcc and the system's -lc. 
+     Finally we support parralleli-mark for the SMP DG/UX machines.
+     To build the garbage collector do:
+      
+      ./configure --enable-parallel-mark
+      make
+      make gctest
+
+     Before you run "gctest" you need to set your LD_LIBRARY_PATH
+     correctly so that "gctest" can find the shared library libgc.
+     Alternatively you can do a configuration
+
+      ./configure --enable-parallel-mark --disable-shared
+  
+     to build only the static version of libgc.
+  
+     To enable debugging messages please do:
+     1) Add the "--enable-full-debug" flag during configuration. 
+     2) Edit the file linux-threads.c and uncommnect the line:
+
+     /* #define DEBUG_THREADS 1 */ to ---> 
+
+     #define DEBUG_THREADS 1
+
+     Then give "make" as usual.
+    
+     In a machine with 4 CPUs (my own machine) the option parallel
+     mark (aka --enable-parallel-mark) makes a BIG difference.

+From: Margaret Fleck
+
+Here's the key details of what worked for me, in case anyone else needs them.
+There may well be better ways to do some of this, but ....
+   -- Margaret
+
+
+The badge4 has a StrongArm-1110 processor and a StrongArm-1111 coprocessor.  
+
+Assume that the garbage collector distribution is unpacked into /home/arm/gc6.0,
+which is visible to both the ARM machine and a linux desktop (e.g. via NFS mounting).
+
+Assume that you have a file /home/arm/config.site with contents something like the
+example attached below.  Notice that our local ARM toolchain lives in
+/skiff/local.
+
+Go to /home/arm/gc6.0 directory.  Do
+  CONFIG_SITE=/home/arm/config.site ./configure --target=arm-linux
+--prefix=/home/arm/gc6.0
+
+On your desktop, do:
+   make
+   make install
+The main garbage collector library should now be in ../gc6.0/lib/libgc.so.  
+
+To test the garbage collector, first do the following on your desktop
+   make gctest
+   ./gctest
+Then do the following on the ARM machine
+   cd .libs
+   ./lt-gctest
+
+Do not try to do "make test" (the usual way of running the test
+program).  This does not work and seems to erase some of the important
+files.
+
+The gctest program claims to have succeeded.  Haven't run any further tests
+with it, though I'll be doing so in the near future.

+ - Added SPARC V9 (64-bit) support.  (Thanks to Jeff Sturm.)
+ - Restructured the way in which we determine whether or not to keep

+   now zero on all platforms.  Added SAVE_CALL_NARGS parameters.
+   If possible, use execinfo.h to capture call stack.  (This should

+ - Redefined strdup if -DREDIRECT_MALLOC is given.
+ - Changed incremental collector and MPROTECT_VDB implementation so that,
+   under favorable conditions, pointerfree objects are not protected.
+   Added GC_incremental_protection_needs() to determine ahead of time whether

+ - Added GC_MARKERS environment variable to allow use of a single marker

+ - Collect much less aggressively in incremental mode with GC_TIME_UNLIMITED.
+   This is really a purely generational mode, and we can afford to

+ - Remove read() wrapper for MPROTECT_VDB.  It was causing more harm than

+ - Allocating uncollectable objects with debug information sometimes
+   allocated objects that were one byte too small, since uncollectable
+   objects don't have the extra byte added at the end.  (Thanks to
+   Wink Saville for pointing this out.)
+ - Added a bit more assertion checking to make sure that gcj objects
+   on free lists never have a nonzero second word.
+ - Replaced BCC_MAKEFILE with an up-to-date one.  (Thanks to 
+   Andre Leiradella.)
+ - Upgraded libtool, cinfigure.in and some related files to hopefully
+   support NetBSD/SPARC.  (Thanks to Adrian Bunk.)  Unfortunately,
+   libtool 1.4.2 seemed to be buggy due to missing quotes in several
+   "test" invocations.  Fixed those in the ltmain.sh script.
+ - Some win32-specific patches, including the introduction of
+   GC_CreateThread.  (Thanks to Adam Megacz.)
+ - Merged in gcj changes from Anthony Green to support embedded systems.
+ - Tried to consistently rename preprocessed assembly files with a capital
+   .S extension.
+ - Use alpha_mach_dep.S on ALPHA again.  It doesn't really matter, but this
+   makes our distribution consistent with the gcc one, avoiding future merge
+   problems.
+ - Move GET_MEM definition into gcconfig.h.  Include gcconfig.h slightly
+   later in gc_priv.h to avoid forward references to ptr_t.
+ - Add some testing of local allocation to test.c.
+ - Change definition of INVALID_QTID in specific.h.  The -1 value was used
+   inconsistently, and too likely to collide with a valid stack address.
+   Some general clean-up of specific.[ch].  Added assertions.  (Thanks
+   to Michael Smith for tracking down an intermittent bug to this
+   general area.  I'm not sure it has been squashed yet, however.)
+ - On Pthread systems it was not safe to call GC_malloc() between fork()
+   and exec().  According to the applicable standards, it doesn't appear
+   to be safe to call malloc() or many other libc functions either, thus
+   it's not clear this is fixable.  Added experimental support for
+   -DHANDLE_FORK in linux_threads.c which tries to support it.  It may
+   succeed if libc does the right thing.  I'm not sure whether it does.
+   (Thanks to Kenneth Schalk for pointing out this issue.)
+ - Documented thread local allocation primitives to require an
+   explicit GC_init call.  GC_init_parallel is no longer declared to
+   be a constructor function, since that isn't portable and often
+   seems to lead to initialization order problems.
+ - Changed gc_cpp.cc and gc_cpp.h in one more attempt to make them
+   compatible with Visual C++ 6.  (Thanks to Wink Saville for the
+   patch.)
+ - Some more patches for Linux on HP PA-RISC.
+ - Added include/gc_allocator.h.  It implements (hopefully) standard
+   conforming (as opposed to SGI-style) allocators that allocate
+   collectable (gc_allocator) or GC-traceable, but not collectable
+   (traceable_allocator) objects.  This borrows heavily from libstc++,
+   which borrows heavily from the SGI implementation, this part of
+   which was written by Matt Austern.  Changed test_cpp.cc to very
+   minimally test this.
+ - On Linux/X86, retry mmap with a different start argument.  That should
+   allow the collector to use more (closer to 3GB) of the address space.
+   (Thanks to Jeffrey Mark Siskind for tracking this down.)
+ - Force 64 bit alignment with GCJ support.  (Reflects Bryce McKinley's
+   patch to the gcc tree.)
+ - Refined the choice of sa_handler vs. sa_sigaction in GC_dirty_init
+   to accomodate some glibc5 systems.  (Thanks to Dan Fandrich for the
+   patch.)
+ - Compensated for the fact that current versions of glibc set
+   __libc_stack_end incorrectly on Linux/IA64 while initialization code
+   is running.  This could cause the collector to miss 16 bytes of
+   the memory stack if GC_malloc or friends where called before main().
+ - Mostly integrated Takis Psarogiannakopoulos' port to DG/UX Inix 86.
+   This will probably take another iteration to work, since his
+   patch conflicted with the libtool upgrade. 
+ - Added README.arm.cross containing some information about cross-
+   compiling to an ARM processor from Margaret Fleck.
+
+Since 6.1alpha4:
+ - Added GC_finalizer_mem_freed, and changed some of the code that
+   decided on heap expansion to look at it.  Memory explicitly
+   deallocated by finalizers essentially needs to be counted as reclaimed
+   by the GC.  Otherwise there are cases in which the heap can grow
+   unboundedly.  (Thanks to Mark Reichert for the test case.)
+ - Integrated Adam Megacz patches to not scan dynamic libraries if
+   we are compiling with gcc on win32.  Otherwise we need structured
+   exception handling to deal with asynchronously unmapped root
+   segments, and gcc doesn't directly support that.
+ - Integrated Anthony Green's patch to support Wine.
+ - GC_OPERATOR_NEW_ARRAY was misspelled OPERATOR_NEW_ARRAY in several
+   places, including gc_cpp.cc.  (Thanks to Wink Saville for pointing
+   this out.)
+ - Integrated Loren James Rittle's Alpha FreeBSD patches.  In
+   response to Richard Henderson's suggestion, these also
+   changed the declarations of symbols like _end on many platforms to
+   that they wouldn't mistakenly be declared as short data symbols.
+ - Integrated changes from the Debian distribution.  (Thanks to Ryan Murray
+   for pointing these out.)  Fix C++ comments in POWERPC port.  Add ARM32
+   incremental GC support.  Get rid of USE_GENERIC_PUSH_REGS for alpha/Linux,
+   this time for real.  Use va_copy to get rid of cord printf problems
+   (finally).
+ - Close file descriptor used to count cpus.  Thanks to Jeff Sturm for
+   pointing out the omission.
+ - Don't just drop gcj free lists in GC_start_reclaim, since that can
+   eventually cause the marker to see a bogus mark descriptor in the 
+   dropped objects.  The usual symptom was a very intermittent segmentation
+   fault in the marker.  This mattered only if one of the GC_gcj_malloc
+   variants was used.  (Thanks to Michael Smith, Jeff Sturm, Bryce
+   McKinley and Tom Tromey for helping to track this down.)
+ - Fixed Linux and Solaris/64 SPARC configuration.  (Thanks to David Miller,
+   Jeff Sturm, Tom Tromey, and Christian Joensson.)
+ - Fixed a typo in strdup definition.  (Thanks to Gerard A Allan.)
+ - Changed Makefile.direct to invoke $(CC) to assemble alpha_mach_dep.S.
+   This is needed on Linux.  I'm not sure whether it's better or worse
+   on Tru64.
+ - Changed gc_cpp.h once more to declare operator new and friends only in
+   a Microsoft environment.  This may need further fine tuning.  (Thanks to
+   Johannes Schmidt for pointing out that the older code breaks on gcc3.0.4.)
+ - Don't ever override strdup if it's already macro defined.  (Thanks to
+   Adnan Ali for pointing out the problem.)
+ - Changed gc_cpp.h yet again to also overload placement new.  Due to the
+   C++ overloading rules, the other overloaded new operations otherwise hide
+   placement new, which causes many STL uses to break.  (Thanks to Reza
+   Shahidi for reporting this, and to Matt Austern for proposing a fix.)
+ - Integrated cygwin pthreads support from Dan Bonachea.
+ - Turn on DYNAMIC_LOADING for NetBSD.  (Thanks to Krister Walfridsson.)
+ - Changed printing code to print more complete GC times.
+ - Applied Mark Mitchell's Irix patch to correct some bitrot.
+ - Clarified which object-printing routines in dbg_mlc.c should hold
+   the allocation lock.  Restructured the code to allow reasonable object
+   printing with -DREDIRECT_MALLOC.
+ - Fix the Linux mmap code to always start with 0x1000 as the initial hint.
+   Minor patches for 64-bit AIX, particularly to STACKBOTTOM.
+   (Thanks again to Jeffrey Mark Siskind.)
+ - Renamed "SUSPENDED" flag for Solaris threads support to avoid a conflict
+   with a system header. (Thanks to Philp Brown.)
  
 
 To do:
+ - --enable-redirect-malloc is mostly untested and known not to work
+   on some platforms. 
+ - The win32 collector ends up tracing some (most?) objects allocated with
+   the system allocator, in spite if the fact that it tries not to.
+   This costs time and space, though it remains correct.
+   We need a way to identify memory regions used by the system malloc(),
+   or an alternate way to locate dll data areas.  A very partial
+   workaround is to use GC_malloc_atomic_uncollectable() instead of
+   the system malloc() for most allocation.
