# configure.host
# This shell script handles all host based configuration for libgcj.
# 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:
# libgcj_cflags Special CFLAGS to use when building
# libgcj_cxxflags Special CXXFLAGS to use when building
# libgcj_javaflags Special JAVAFLAGS to use when building
# libgcj_interpreter If the bytecode interpreter supports this platform.
# enable_java_net_default If java.net native code should be enabled by
# default.
# enable_hash_synchronization_default If hash synchronization should be
# enabled by default.
# sysdeps_dir Directory containing system-dependent headers
# slow_pthread_self The synchronization code should try to avoid
# pthread_self calls by caching thread IDs in a hashtable
# can_unwind_signal Set to "yes" if the EH unwinder supports throwing
# from a signal handler.
