This looks close to good (although I have no time to try it right now --
I just
browsed through). But please read on.
The tix and itcl missing from skipdirs were probably forgotten to be
added ages ago.
Issuing a warning and disabling gdbtk if no X11 is available makes sense
on UNIX systems.
The problem I see with this is that it disables gdbtk on systems where
X11 is not used
by Tcl, like on Cygwin or Windows native. So, you'll have to check if
it is a Unix host
or not before disabling gdbtk.
