Hi, Your change: 1998-12-07 Jason Merrill <jason@yorick.cygnus.com> * decl.c (init_decl_processing): If neither -fpermissive or -pedantic were specified, set flag_pedantic_errors. breaks glibc. That is a code fragment generated by autoconf. With gcc 2.95, I got # gcc -S bar.cc In file included from bar.cc:5: /usr/include/stdlib.h:520: declaration of `exit(int)' throws different exceptions bar.cc:2: previous declaration here egcs 1.1.2 only gives a warning. It should be fixed in gcc 2.95. How does this patch sound? --- ../../import/gcc-2.95/egcs/gcc/cp/decl.c Fri Jul 9 08:32:50 1999 +++ gcc/cp/decl.c Wed Jul 14 12:51:56 1999 @@ -3516,7 +3516,8 @@ duplicate_decls (newdecl, olddecl) TREE_TYPE (olddecl) = build_exception_variant (newtype, TYPE_RAISES_EXCEPTIONS (oldtype)); - if ((pedantic || !
