The second case is true. The VFW Api has been included in Mings Windows 
headers and you get lots of redefinition warnings also when doing an MSys 
build. And there is a real show stopper, in
BOOL VFWAPI capGetDriverDescriptionA (WORD wDriverIndex, LPSTR lpszName,
              int cbName, LPSTR lpszVer, int cbVer);
it should be UINT wDriverIndex. This produces the error. So its basic C.

I think that a bit more can be removed than done by your patch. If it helps I 
can try on Windows this evening and check what can be removed whitout doing 
any harm.
