Re: building latest on FreeBSD 6.0

__STDC_ISO_10646__ indicates that wchar_t contains UCS-4 code  
points.  It isn't true on Windows where wchar_t is UTF-16 or on some  
Asian variants of Solaris.  wchar_t on Mac OS/X is not explicitly  
defined.   I'll look at your changes and see if I can generalize them.
