It looks like the definition of the std::wstring class is commented out on
FreeBSD 4 because <cwctype> is missing. You could try adding this wherever
necessary:
	#include <cwchar>
	typedef basic_string<wchar_t> std::wstring;

It will work for most simple things, but not stream I/O.

Another workaround is to uncomment the definition in g++/string, un-#if 0
the definition of string_char_traits <wchar_t> in g++/std/straits.h,
change the #include line preceding it to <cctype>, and change iswspace() to
isspace(). This is not as much of a hack as it sounds, since the 4.4BSD ctype
functions accept wide characters, but it's obviously not something a port
should be doing.
