2# --------------------------
3# Ensure that the configuration variables for the GNU Java Compiler compiler
4# are suitably defined.  These variables are subsequently used by _LT_CONFIG
5# to write the compiler configuration to `libtool'.  Locally modified to
6# run its tests on C programs, because we cannot link Java programs until
7# we have finished building libjava.
