Hi I'm writing a cross platform open GL application, doing my development on linux, and porting to windows (using glut for windowing)

The only openGL problem I've had so far with the porting is with the call:
>>
glEnable(GL_RESCALE_NORMAL);
<<

which gets me:
>>
G:\Programming\mesaFace\main.cpp(51) : error C2065: 'GL_RESCALE_NORMAL' : undeclared identifier
<<

anybody know what's up with that? My theory is that this is part of the openGL 1.2 spec. and I perhaps only have 1.1 on my windows installation. I've looked for a download to fix it but no luck.

So if someone can help me out, please do.

Additionally, I'm about to start implementing a gui, and I was thinking of using MUI (remember cross platform is key here). I have also considered gtk. Anyone care to share an opinion/experience?
