# 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_cflags=""

# We should set -fexceptions if we are using gcc and might be used
# inside something like gcj.  This is the zeroth approximation:
if test :"$GCC": = :yes: ; then
    gc_cflags="${gc_cflags} -fexceptions"
else
