Subject: Disable -Wunsafe-loop-optimizations
X-Git-Tag: 1.0.71~18
X-Git-Url: http://git.annexia.org/?a=commitdiff_plain;h=6c8a69c602643ae3102c263148a94559d6594381;p=libguestfs.git

Disable -Wunsafe-loop-optimizations

This warning indicates that GCC could not do a particular sort
of loop optimization.  It pops up randomly in certain forms of
looping code, and seems safe to ignore.
