I've come to the same conclusion as to about where they should be
located.  However, I think that the OpenGL package should be what puts
them there.  I can be convinced otherwise though.  If Andre Bleau or
anyone else want's to consider matching lib/*.def and include/GL/*.h
files to be included in the w32api package then please upload the
patches with appropriate ChangeLog entries at and
I'll take a look.
