Actually, around 1600 with future libgnatvsn patches.

See at least the debian/changelog entry of 4.9-20140330-1.
If the dependency can be dropped, I suggest that we at least isolate
all changes affecting src/Makefile.in into a single patch towards the
end of the patch queue, so that refreshing the patches only requires
one autogen run, and the noise does not pollute interesting files.
