+# 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.
