Jakub wrote a larger patch for the rest of the X libraries, etc.
to make the whole shebang hide internal symbols and reduce
relocation processing overhead also.  This is the patch I was 
referring to above, however it's great to see the Mesa stuff 
eventually got integrated too.

On a side note, I talked with ajax and others in IRC yesterday a
bit about the above, and he also mentioned Mesa had been cleaned
up a bit by idr.

One question I neglected to ask, was if libGL is now prelinkable,
or if further work is required to implement all of the
functionality from Jakub's original Mesa patches?

TIA
