I've recently been improving some GCC-based static analysis in Gnulib, 
and syncing from Gnulib to diffutils meant that you have a bit of a 
work-in-progress there. I plan to make further such changes soon.

The Gnulib work already installed is conservative and I see no harm in 
releasing what we've got in diffutils now. I'm sending this email mainly 
to give you a heads-up that more Gnulib changes are coming.

FWIW attached are the diffutils patches I have so far. They assume the 
abovementioned Gnulib work-in-progress and this should not be installed 
in diffutils yet. Most likely more minor diffutils patches will be 
needed once I've finished the Gnulib changes I have in mind.

Until today I've been using the Gnulib work-in-progress on grep rather 
than on diffutils. I've found one memory leak there and hope to find 
more bugs - after all, that's the point of all this. I didn't find any 
diffutils bugs in my brief run-through today.
