HOWEVER, that is not the only issue here.
Why is master is picking the BUILTIN (__sync) atomics (as

on which distro are you running ?
are you compiling on a 64 bit distro to generate a 32 bit library ?
it seems we are currently only testing a atomic on a long (32 bits on a
32 bits arch) and
then incorrectly assume it works also on 64 bits (!)

`__sync_add_and_fetch_8'
This is impacting PRs that I am being asked to test (e.g. 1643).
