the version number of the next stable release of gtk/glib is
very decidedly going to be 2.0 ;)

the GType/GObject/GParam/GValue stuff is already there for
the most part in CVS HEAD. it's certainly mature enough to
play around with. the GSignal code is still hiding in my
local tree, since i haven't yet gotten all the bits and
quirks of it right.

for the time being, you may just link your application against
gtk+, 1.2.x even, surpass gtk_init() and call gtk_type_init()
and gtk_signal_init() instead.
that provides you with GtkObject and the gtk signal system,
which GObject and GSignal are pretty similar to.
support for the GtkSignal (plus some minor extensions) will
soon go into CVS. the only thing you probably wouldn't
want to use too extensively is the GtkArg system, it's
going to be completely replaced by GParam/GValue (module
some crippled compatibility cruft).
