Well, I didn't look at WCHAR when I wrote the PowerPC optimized
memXXX functions, so I guess these don't support WCHAR.

Had a quick look at WCHAR support and it looks like the only thing
one has to do for the PowerPC functions is to multiply size_t with
sizeof(wchar_t) to make them support wchar. Would be great if someone
that
knows WCHAR could confirm that.

You might want to add __ versions of these functions that are hidden(see
PowerPC). The
__ functions are for internal libc use. This will reduce relocs inside
libc and will make libc
smaller and faster.
