This patch will have to be revised after upstream develops real fix. Current
patch has an impact on performance.

--- Comment #1 from Petr Pisar  ---
This has been worked around by adding -fwrapv to ccflags with these two
commits:

commit 869747506fd0081f6c7eed149ec6f7adbcc4d5b1
Author: H.Merijn Brand 
Date:   Wed Apr 9 11:16:55 2014 +0200

gcc 4.9 by default does some optimizations that break perl (#121505)

Patch by Tony Cook

commit 00051dd553979bd2a1dee100c324b59ee76a49e7
Author: H.Merijn Brand 
Date:   Wed Apr 9 12:31:23 2014 +0200

-fwrapv is broken prior to gcc-4.3 (googled and patched by Zefram)

The real code fix is demanded for perl-5.22.
