So, I'm back from vacation and trying to digest this all ... and the first
thing I ran into is that the new ctype code in test/getcwidth.c uses
__WCHAR_MAX__ ... which is not defined by MacOS X!  It looks like POSIX
officially uses WCHAR_MAX.  I will admit that I am always confused why
some preprocessor symbols use __ around them and some do not (I am sure
there is a reason for when to use it, it just is not obvious to me).  But
since POSIX officially defines WCHAR_MAX, we should use that?
