The Mesa git repo and tarball releases include a few things that 
originate from SGI:

1. Header files such as GL/glu.h (plus some Khronos headers like glext.h)

2. The libGLU library

3. The client-side GLX library code (, when Mesa's build with 
GLX/DRI support), some of which has changed a lot since 1999/2000.

Note that core Mesa doesn't directly rely on any SGI header files or the 
OpenGL Sample Implementation.
