2004-01-20 Bruce Korb <bkorb@gnu.org>
* fixinc/inclhack.def(math_exception): bypass only for glibc.
(matherr_decl): rename & relocate as exception_structure.
This fix must precede the math_exception fix.
2004-01-20 Roger Sayle <roger@eyesopen.com>
* fold-const.c (fold_convert): Rename to fold_convert_const.
