    short is a c++ keyword, and the compiler thinks that you have redefined it in opengl.cpp somewhere. Probably, you have opengl.lib & .dll and should include the lib in the project not the .cpp -- but this is a guess (I don't remember ever having an opengl.cpp that was used in a project, it exists only to compile the library and probably has a *very* special makefile -- remember, this stuff was created on unix and is old enough to be a little strange).
