# 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.
