Hi VZ:

Below is a very trivial 1 line patch for "mimetype.h" that does the trick!
With it I can compile all of my user applications using the unsigned-char
options for the C/C++ compilers.  From what I can tell, the "+"
overloaded operator for wxString had difficulties with the wxT macro,
which that context should output a wxChar, so by explicitly casting it,
the problem went away.

I would appreciately your assistance submitting this patch, since I
am not familar with patch submission procedure.  I hope that this
patch can match it into the 2.8.0rc2 release.

Thanks in advance,
Alicia.
