I'm attaching 19990407-1.i and _default_types.h. From what I can see, the
latter is considered a system header by the preprocessor just as before, still
a warning is now emitted that wasn't before. A -Wno-system-headers has no
effect.
According to -v, the preprocessor is invoked as "/tmp/bad0516b/gccobj/gcc/cc1
