According to the ISO C standard, the meaning of wchar_t
is implementation-defined.  'typedef char wchar_t;' is
a valid definition (and IIRC, IRIX 4 did just this).

On IRIX 5 and IRIX 6, wchar_t is big enough to hold any Unicode
character, but I can't find anything that says whether or
not wchar_t's are actually interpreted as such.  It appears
to depend on the current locale.
