I think if you move APIENTRY to the *end* of the function prototype then
it will work with g++ (and gcc), but, of course, it will stop working with
other compilers I suspect. If you are just using gcc and g++ then no
problem, otherwise make separate copies of those headers for gcc/g++.
WINGDIAP const GLubyte * glGetString( GLenum name) APIENTRY;
Looks strange, but I think it will work.
This is, I think, a bug in the C++ parser, and I have no idea if/when it
will be fixed.
Good luck,
Colin.
