MAX_PATH mess fix

[Steven Edwards]

It seems mingw tries to include stdlib.h after windef.h in the build 
process and that was the result of the warnings/error.

By making this change I don't have to change any of the other headers
That depend on MAX_PATH (winnls,wingdi) by adding stdlib.h in them. 
I don't know if its right by the wine project standards but now I can 
compile 90% of the wine dll sources without warrnings/errors from 
stupid MAX_PATH. If someone has a better way please cvs diff -u me =)

Thanks 
Steven
