I don't see any difference, still the same error when linking.
Unfortunately I'm not really familiar with configure scripts.
Not sure what your exact intention was for with this patch.
Was the idea to determine _FILE_OFFSET_BITS?
It looks to me as if _FILE_OFFSET_BITS is still 64 and this will cause
the test for prpsinfo to fail.

Besides I still think that elf.c should provide these 2 functions
either always or procfs.c should use the same defines as elf.c

Thanks
