This is true for the latest w32api-2.5.tar.gz headers (20040515),
but I used just the older default cygwin mingw headers from cygwin 
setup: gcc-mingw-core-20031020-1.tar.bz2, which has no wrong
/usr/include/mingw/ocidl.h

I'll try to trace that down, since the idea of my build is to use it 
with the cygwin setup version, and not the latest mingw builds (3.4.x).
