As far as I know Win32 API doesn't have such definitions due to its
difference from Unix. Thus it's impossible to have them defined (and
the functionality they control implemented) using MinGW header files.

I had done limited porting of SANE under native Win32. How should I
submit my work for review - the patch alone, CVS branch etc?
