+ * G++ multiple inheritance compiler problem
+
+In the 2.3.2 release of gcc/g++, how the compiler resolves multiple
+inheritance lattices was reworked to properly discover ambiguities.  We
+recently found an example which causes this new algorithm to fail in a
+very subtle way, producing bad debug information for those classes.
+The file 'gcc.patch' (in this directory) can be applied to gcc to
