Not as far as I know.

That's why it says it isn't supported;-)

You mean, like from Microsoft (for it to be official) :-)? Is there any
"official" GTK+ for Solaris, HP-UX or AIX? (Hmm, for Solaris I guess
there will be, as Sun will ship GNOME with Solaris 9.)

Of course, their widget sets was written for it (or for 16-bit
graphics, even) from the beginning.

They also have much more resources, and their graphics APIs presumably
weren't originally written to just thinly hide Xlib?

Patches gratefully accepted. There is some code in there to handle
256-colour mode (as you noticed, that is used only if that
GDK_WIN32_ENABLE_BROKEN_PSEUDOCOLOR_VISUAL environment variable is
set). But it's been a long time since I have bothered to look at it. I
can't say how badly broken it is, whether just patching here and there
would work, or whether starting from scratch is the only option.
