PATCH: Remove unused ITCL_DIR variable in libgui config.

[Mo DeJong <mdejong at cygnus dot com>]

Hi all.

While looking at libgui, I noticed what seems to be an unused
variable. The ITCL_DIR variable set in libgui configure.in is
not used anywhere in libgui. I can't help but think this is
just some old cruft that never got removed. There was a
comment about ITCL_SH in the configure.in file, but
that does not seem to matter since ITCL_SH is defined
with a fully qualified path in itclConfig.sh.

% grep ITCL_SH itclConfig.sh 
ITCL_SH='/tmp/build_insight/itcl/itcl/unix/itclsh'

This came up because as part of the Tcl/Tk upgrade, we are
moving to Itcl 3.2 which no longer builds in a unix or win
subdir. I am currently trying to remove any code that
uses the old build structure so that the transition
is as painless as possible.

Here is the ChangeLog entry that implements the change
along with the patch for configure.in:

P.S.

Does anyone know what version of automake should be used to
regen for code on sources.redhat.com? Should the maintainer-tools
module be used? Some of the current configure scripts seem to
have been generated by autoconf 2.13 which is why I ask.

cheers
