1 # _LT_LANG_GCJ_CONFIG([TAG])
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.
