So that should be reported as a bug in the package parsing the version
numbers.

libtool 1.3081 comes from ChangeLog entry 3081; the libtool authors wanted
to have a monotonically increasing number in every development build (not
present in formal release builds) to make it easier to track exactly
_which_ development build you are using.  The package number, 2.2.7a, is
only bumped for formal releases, with odd letters (aceg...) designating
development alpha snapshots, even letters (bdfh...) designating betas, and
the absence of a letter being a stable release.

True, cygwin is a bit unusual for using a development snapshot, rather
than a formal release, of libtool, but that's because there hasn't yet
been a formal release containing the latest round of patches necessary for
use on cygwin.
