# 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.
gc_cflags=""

# We should set -fexceptions if we are using gcc and might be used
# inside something like gcj. This is the zeroth approximation:
