-/*
- * For each architecture and OS, the following need to be defined:
- *
- * CPP_WORD_SZ is a simple integer constant representing the word size.
- * in bits.  We assume byte addressibility, where a byte has 8 bits.
- * We also assume CPP_WORD_SZ is either 32 or 64.
- * (We care about the length of pointers, not hardware
- * bus widths.  Thus a 64 bit processor with a C compiler that uses
- * 32 bit pointers should use CPP_WORD_SZ of 32, not 64. Default is 32.)
- *
- * MACH_TYPE is a string representation of the machine type.
- * OS_TYPE is analogous for the OS.
- *
- * ALIGNMENT is the largest N, such that
- * all pointer are guaranteed to be aligned on N byte boundaries.
- * defining it to be 1 will always work, but perform poorly.
- *
- * DATASTART is the beginning of the data segment.
- * On UNIX systems, the collector will scan the area between DATASTART
- * and DATAEND for root pointers.
- *
- * DATAEND, if not &end.
- *
- * ALIGN_DOUBLE of GC_malloc should return blocks aligned to twice
- * the pointer size.
- *
- * STACKBOTTOM is the cool end of the stack, which is usually the
- * highest address in the stack.
- * Under PCR or OS/2, we have other ways of finding thread stacks.
- * For each machine, the following should:
- * 1) define STACK_GROWS_UP if the stack grows toward higher addresses, and
- * 2) define exactly one of
- *	STACKBOTTOM (should be defined to be an expression)
- *	HEURISTIC1
- *	HEURISTIC2
- * If either of the last two macros are defined, then STACKBOTTOM is computed
- * during collector startup using one of the following two heuristics:
- * HEURISTIC1:  Take an address inside GC_init's frame, and round it up to
- *		the next multiple of STACK_GRAN.
- * HEURISTIC2:  Take an address inside GC_init's frame, increment it repeatedly
- *		in small steps (decrement if STACK_GROWS_UP), and read the value
- *		at each location.  Remember the value when the first
- *		Segmentation violation or Bus error is signalled.  Round that
- *		to the nearest plausible page boundary, and use that instead
- *		of STACKBOTTOM.
- *
- * If no expression for STACKBOTTOM can be found, and neither of the above
- * heuristics are usable, the collector can still be used with all of the above
- * undefined, provided one of the following is done:
- * 1) GC_mark_roots can be changed to somehow mark from the correct stack(s)
- *    without reference to STACKBOTTOM.  This is appropriate for use in
- *    conjunction with thread packages, since there will be multiple stacks.
- *    (Allocating thread stacks in the heap, and treating them as ordinary
- *    heap data objects is also possible as a last resort.  However, this is
- *    likely to introduce significant amounts of excess storage retention
- *    unless the dead parts of the thread stacks are periodically cleared.)
- * 2) Client code may set GC_stackbottom before calling any GC_ routines.
- *    If the author of the client code controls the main program, this is
- *    easily accomplished by introducing a new main program, setting
- *    GC_stackbottom to the address of a local variable, and then calling
- *    the original main program.  The new main program would read something
- *    like:
- *
- *		# include "gc_private.h"
- *
- *		main(argc, argv, envp)
- *		int argc;
- *		char **argv, **envp;
- *		{
- *		    int dummy;
- *
- *		    GC_stackbottom = (ptr_t)(&dummy);
- *		    return(real_main(argc, argv, envp));
- *		}
- *
- *
- * Each architecture may also define the style of virtual dirty bit
- * implementation to be used:
- *   MPROTECT_VDB: Write protect the heap and catch faults.
- *   PROC_VDB: Use the SVR4 /proc primitives to read dirty bits.
- *
- * An architecture may define DYNAMIC_LOADING if dynamic_load.c
- * defined GC_register_dynamic_libraries() for the architecture.
