# This shell script handles all host based configuration for libgfortran.
# It sets various shell variables based on the the host triplet.
# You can modify this shell script without rerunning autoconf/aclocal/etc.

#
# It uses the following shell variables as set by config.guess:
# host The configuration host (full CPU-vendor-OS triplet)
# host_cpu The configuration host CPU
# host_os The configuration host OS
#
#
# It sets the following shell variables:
#
# fpu_host FPU-specific code file, defaults to fpu-generic.
# DEFAULTS
