GL_MAX_TEXTURES_UNITS_ARB dont exist! Can´t use glGetInteger!

The compiler says GL_MAX_TEXTURES_UNITS_ARB dont exist. How can I get the max number of textures that my version supports?
Heeeeelp!

#define GL_MAX_TEXTURE_UNITS_ARB 0x84E2
But if you needed that, then I suspect you will need a lot more too. Sounds like you need to get an updated gl header with the extensions defined.
