A few improvements for your consumption:
1. g2c now uses the ctags that comes with just about every emacs distro out there. No more strange dependencies!
2. g2c will now generate a main program file, using .c for the file name. Entries will be added/commented out based on the top-level widget's visibility (in glade).
3. Automatically updates po/POTFILES.in and
4. Modifications to the automake/autoconfig stuff.
5. Other minor updates/fixes.
