I do not think this patch is anywhere near complete.  Particularly the
stddef.h changes.

I think you need to look at every hunk of code in stddef.h which uses or
defines BSD_SIZE_T, BSD_WCHAR_T & BSD_PTRDIFF_T and do the right thing.  In
some cases that may mean deleting the references, or it may mean changing
them.

If they are correct, I need the analysis which shows they are correct.  If they
are obsolete, I need that analysis and a patch to remove all the obsolete uses,
not just some of them.

In general, given the uglyness of stddef.h a patch to it needs to be well
understood.

I believe you also need update varargs.h in a manner similar to stdarg.h.

I believe the t-freebsd change it OK, but I'm not going to install it since
doing so without the associated stdarg.h, varargs.h and stddef.h changes will
cause more problems than it solves.
