How should these patches be approached?  On windows, it would probably
be easiest to use the MS generic text routines: _tcslen instead of
strlen, for example, and to rely on the _UNICODE preprocessor symbol to
map this function to strlen or wcslen.  Is there a similar thing in the
non-windows world?
