From: Werner Koch <wk@gnupg.org>

Subject: Add assuan_check_version and ASSUAN_VERSION_NUMBER.

* src/assuan.c (assuan_check_version): New.
(digitp, parse_version_number, parse_version_string)
(compare_versions): New.  Taken from libksba.
* configure.ac (VERSION_NUMBER): New ac_subst.
* src/Makefile.am (assuan.h): Pass VERSION and VERSION_NUMBER to
mkheader.
* src/assuan.h.in (ASSUAN_VERSION, ASSUAN_VERSION_NUMBER): New macros.
(assuan_check_version): New prototype.
* src/libassuan.def, src/libassuan.vers: Add assuan_check_version.
* src/mkheader.c (write_special, main): Support version and
version_number.
* tests/version.c: New.
* tests/Makefile.am (TESTS): Add version.
--

All our other libs have a version number check, thus we should have
one in Libassuan as well.
