Bug #: 52929
Summary: use of undeclared identifier '__ATOMIC_ACQ_REL'
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: o...@xeviox.com
The error occurs on Archlinux x64 with everything updated.
The project uses Qt 4.8.x which was installed using the package manager. I also
tried compiling with clang, which came up with the same error.
The following error breaks the compile:

I also tried to find the define using grep:
