*Nod*. 3) has created a maintenance nightmare for us/me on ioq2 where the 
Linux people would patch and commit to CVS without backporting the diffs 
to the Solaris files, thereby breaking the port.. I'll go with 2) as per 
your recommendation and remove the solaris_glimp file I just created.. :)

Solaris OpenGL has the GL_ARB_multitexture definitions (lots of 
glMultiTexCoord*) but these things "PFNGLM" do not appear anywhere..

Do you want me to post the Sun OpenGL headers somewhere so we can examine 
them and maybe devise some more portable way to do this?
