# _LT_LANG_GCJ_CONFIG([TAG])
# --------------------------
# Ensure that the configuration variables for the GNU Java Compiler compiler
# are suitably defined.  These variables are subsequently used by _LT_CONFIG
# to write the compiler configuration to `libtool'.  Locally modified to
# run its tests on C programs, because we cannot link Java programs until
# we have finished building libjava.
