I took a quick look at gcc 4.0.1's build scripts (what I'm running). It
would appear that gcc blindly replaces limits.h, float.h, iso646.h,
stdarg.h, stdbool.h, stddef.h, varargs.h, and unwind.h. Of these,
limits.h is the only one that then includes the native header. They
aren't modified by fixincludes. fixincludes takes a hack at the other
headers that end up in gcc's include directory.
