Issue #2559 has been updated by marino.
Heh, I was working under the assumption that this test worked elsewhere and I was going to test it on the latest FreeBSD.
I also assumed that -fpic wasn't wanted because the error message was so obvious about the problem.
Bug #2559: gcc -pie and __builtin_popcount causes
I found that __builtin_popcount is not usable with -pie option for gcc.
