Total hack to allow gcc32 to build on -CURRENT.
This hack makes gcc totally use our stock headers vs. the fixinc'ed ones.
I don't like this change as I don't think there is any chance of getting
this change back into the GCC repository and it is important that the
stock GCC sources will bootstrap on FreeBSD 5.0.
