Pre-release version bump to 0.32.0
Post-release version bump to 0.33.1
test: Fix the win32 build

The win32 build has no config.h, so HAVE_CONFIG_H should be checked
before including it, as in utils.h.
demos/Makefile.am: Move EXTRA_DIST outside "if HAVE_GTK"

Without this, if tarballs are generated on a system that doesn't have
GTK+ 2 development headers available, the files in EXTRA_DIST will not
be included, which then causes builds from the tarball to fail on
systems that do have GTK+ 2 headers available.
