+# configure.host
+
+# This shell script handles all host based configuration for the garbage
+# collector.
+# It sets various shell variables based on the the host and the
+# configuration options.  You can modify this shell script without
+# needing to rerun autoconf.
+
+# This shell script should be invoked as
+#   . configure.host
+# If it encounters an error, it will exit with a message.
+
+# It uses the following shell variables:
+#   host		The configuration host
+#   host_cpu		The configuration host CPU
+#   target_optspace	--enable-target-optspace ("yes", "no", "")
+
+# It sets the following shell variables:
+#   gc_cflags	Special CFLAGS to use when building
+
+# We should set -fexceptions if we are using gcc and might be used
+# inside something like gcj.  This is the zeroth approximation:
