It does the detect the problem (at least for me), but config.status
doesn't fix the Makefile because CONFIG_FILES isn't *exactly* equal to
Makefile.  It had worked for me because automake was kind enough to
run config.status with CONFIG_FILES=Makefile after I had changed
configure.in :-(

Here's a patch for libgcj-2.95:

Index: libjava/ChangeLog
from  Alexandre Oliva  <oliva@dcc.unicamp.br>
	
	* configure.in (CXXFLAGS): The buggy g++ -g work-around was buggy
	itself; check for Makefile *anywhere* in CONFIG_FILES.
	* configure: Rebuilt.

BTW, is anybody working on the g++ -g problem?
