Section placement into C constants

[Luke Trowbridge]

I would like to get a reference to the start of the GOT in my code.  My 
attempt:

extern void __got_start__;
void * const pGot = (void * const)&__got_start__;

However, pGot is assigned zero (not the start of the GOT) even though the
linker map file shows that __got_start__ is assigned the correct value.

If this is even possible, what is the best way to accomplish this outside of
an executable statement?

Thanks,
Luke
