[gtk/more-vs-proj-updates: 12/13] win32/gen-version-items.py: Retrive version info from configure.ac




commit 6a8c6e6299d76536885a22bec52e8cb8ac426f8f
Author: Chun-wei Fan <fanchunwei src gnome org>
Date:   Fri Aug 5 12:56:49 2022 +0800

    win32/gen-version-items.py: Retrive version info from configure.ac
    
    ...and use that info if no version and/or interface age was specified.  This
    way, we can use this script to help bootstrap builds from Visual Studio
    projects directly from a GIT checkout.
