That might work.  It's not #included in very many files, so adding
port/simd.h shouldn't be too bad.  And ascii.h is also pretty inexpensive,
so including it in wchar.c seems permissible, too.  I'm not certain this
doesn't cause problems with libpgcommon, but I don't see why it would,
either.

Does pgrx use ascii.h at all?
