+# 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", "")
+# GCC should be "yes" if using gcc
+
+# It sets the following shell variables:
+# gc_cflags Special CFLAGS to use when building
+# gc_use_mmap Set to "yes" on platforms where mmap should be used instead
+# of sbrk. This will define USE_MMAP.
