Log Message:
Fix multiple useless C99isms.  Should fix the build with GCC 2.95.
Spotted by latest NetBSD 1.6.2/i386 kristerw@'s bulk build.

While here, commit an update that has been laying here for a while.
This should depend on the latest gtk2 to avoid a deadlock when using
SVG themes.  So bump PKGREVISION to 1.
