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. | |
