I should have said works with GnuPG >=2.1 and gpgme >= 1.5.x, since it was
developed using the latest versions of the GnuPG suite.  gpgme_signers_count()
is a function that was added in gpgme 1.5.0.  It should be easy to do a basic
port to GnuPG 2.0 and gpgme 1.4.3 if there is demand.

Does the old gnupg-for-java still compile on your setup?  As far as I
remember, it does not work with GnuPG 2.x at all.  And it is quite bare bones,
we've added a lot of functionality and some tests to gnupg-for-java.

I pushed a commit that declares 1.5.0 as the minimum gpgme version.
