# This file is a shell script fragment that supplies the information
# necessary for a configure script to process the program in
# this directory. For more information, look at ../configure.
# If the language specific compiler does not exist, but the "gcc" directory
# does, we do not build anything. Note, $r is set by the top-level Makefile.
# Note that when we look for the compiler, we search both with and without
# extension to handle cross and canadian cross builds.
# Note that if $norecursion is set we're being called from config.status,
# so don't check for the compiler; we might be doing a make clean.
