When on GCC 4.1 compiling for i386, we don't use the intrinsic version of __sync_add_and_fetch for 64-bit values, but do use the intrinsic of __sync_add_and_fetch for 32-bit values, which leads to a compile failure. I believe this is an extension of CDRIVER-365.

A workaround for this is to compile with "-march=i686", which turns on the compiler intrinsic.
