Cygwin's gpg2 has "-unknown" suffix in version string.

version-to-list function fails to parse this version string and
epg-find-configuration can't find gpg2 as supported one.

This is a bug in the Cygwin build of gnupg2.  I've sent a fix to the Cygwin 
mailing list:

   http://www.cygwin.org/ml/cygwin/2019-05/msg00089.html

Thank you for the investigation.  Actually, the same problem occurs in
MSYS2 and MSYS2/mingw packages.  Furthermore, as far as I tested,
autoreconf on release tarball adds extra "-unknown" in version string
independently of platforms.


I think that two issues are related with my bug report.

#1. Cygwin, MSYS2's gnupg binary has extra "-unknown" in version string
despite of that they should be released version.

I think it is what you've reported to Cygwin ML.


#2. Locally built gnupg binary may become "-unknown" suffix version.

GnuPG's autogen.sh makes "-unknown" suffix version configure script if
source code directory doesn't have .git directory.  If "-unknown"
suffix is a bug as a general thing, I think GnuPG's repository should
be fixed.  If not, I hope vertion-to-list function accepts "-unknown"
suffix.  How do you think?

That's right.  It just happens that the standard procedure for building packages 
on Cygwin is to run autoreconf on the distributed source.

I've now done something similar, but only in `epg-find-configuration',
because this seems to be a problem in the gpg2 config scripts.

Could you test the trunk now and see whether it fixes your problem?
