[Bug c/40172] [4.5 Regression] Revision 147596 breaks bootstrap

The case in toplev.c cannot be fixed without tracking macro expansions somehow,
but I wonder why it warns (multiple times!) for this case:

> ../../trunk/gcc/config/mips/sb1.md:159: error: logical �or� of

David, could you produce a testcase?

Anyway, moved out of Wextra, so bootstrap should be fixed now.
