No it doesn't!

Got it. The cygport-generated diffs don't include patches to the generated
configure scripts, only the *.ac templates, so you need to manually reconf the
sources after applying the patch. Check the cygport script for a list of
which directories need which auto* tool run on them (I haven't tried just
blindly autoreconf'ing the whole lot from top level but in theory that would
work too), and don't forget you need autoconf-2.59 and make-1.9.6.
