Do you know what this code do?
It gets a pointer to the function "glActiveTextureARB", and stores it in 
your "glActiveTextureARB" pointer. If there's already a function defined 
with this name, you just have to rename your pointer variable. Try:

PFNGLACTIVETEXTUREARBPROC MYglActiveTextureARB;
MYglActiveTextureARB = SDL_GL_GetProcAddress("glActiveTextureARB");


And call the MYglActiveTextureARB.
