I reported against 0.8.5 because it's the first version FTBFSing with thi=
s that
I noticed: <http://buildd.debian.org/build.php?arch=3D&pkg=3Dgst-ffmpeg>.

The flag was meant temporarily to sort out optimizations and enhance gcc,=
 and
has been deprecated since 3.3 at least.  It's removal is described at
<http://gcc.gnu.org/gcc-4.0/changes.html> as follows:
"The options -freduce-all-givs and -fmove-all-movables have been disconti=
nued.
They were used to circumvent a shortcoming in the heuristics of the old l=
oop
optimization code with respect to common Fortran constructs. The new (tre=
e) loop
optimizer works differently and doesn't need those work-arounds."

I think it's not important for a 3.3 build, but might enhance the loop
optimizations slightly, if the other loop enhancement options are not pre=
sent,
but I won't test.
