Umm, reading configure.in and the Makefile.am files, that should be
Z-A:A:B-A, where B is the "binary age", the number of releases since
last making a binary incompatible change?

LT_CURRENT=`expr $GTK_MICRO_VERSION - $GTK_INTERFACE_AGE`
LT_REVISION=$GTK_INTERFACE_AGE
LT_AGE=`expr $GTK_BINARY_AGE - $GTK_INTERFACE_AGE`

and

 -version-info $(LT_CURRENT):$(LT_REVISION):$(LT_AGE)

Looking at libtool, shouldn't that be libgtk-X.Y.so.(Z-B).(B-A).A
(where the Z-B is calculated by libtool as "current - age", i.e
(Z-A)-(B-A)?

        linux)
          major=.`expr $current - $age`
          versuffix="$major.$age.$revision"

(That "linux" meaning "version_type", with "linux" being used also for
Solaris, for instance.)
