--- Comment #3 from Manuel Holtgrewe <manuel.holtgrewe@fu-berlin.de> 2011-01-25 16:53:23 UTC ---
Sorry for posting this here again, but could somebody clarify the following,
nevertheless and if this is expected behaviour, close the bug as invalid? In
the future, I'll first try to ask on the list.

Versions 4.4 and 4.5 were built with the same parameters (modulo some
libraries), so my question is: Why are the __sync_fetch* builtins not found in
4.4 by default? Is this related to the configure parameters?
