Your fix worked for all of the missing MAX_PATH errors in winnls.h and
wingdi.h but 
I still get one warning every once and a while.

../include/windef.h:155: warning: `MAX_PATH' redefined
/usr/include/mingw/stdlib.h:62: warning: this is the location of the
previous de
finition

Is this a mingw problem? If so I wil go talk to them, if not then it
just needs 
This before the MAX_PATH define.

#ifdef __MINGW__
#undef MAX_PATH
#endif /* __MINGW__ */

In any case I can live with this warning now that the errors are gone. 
Thanks For the help so far.
