 I consider this a definate bug, and have a patch that papers over the
problem (I don't consider it a 100% true fix). My fix causes gcc to
skip its include directory when -traditional is given. Since other
necessary things may live in there, this isn't a perfect solution, but
sort of adding a -ansi-specific include directory I can't think of
one.

 My patch (apply to cccp.c):
