I've only looked at the patches briefly. However, as they stand, they
would appear to break other platforms. We need to find solutions such
that a single source tree can be used for any platform.

Some specifics:

I'm not sure that we should be explicitly adding /usr/X11R6/bin to
$PATH in init.sh. This should go into the user's ~/.grass.cshrc if
they don't already have /usr/X11R6/bin in their path.

The use of "[exec ls -a [exec pwd]]" in gis_set.tcl should be replaced
by the use of Tcl's "glob" function, e.g.

	foreach i [glob "*"] {

Or, if dotfiles are really required (they probably aren't):

	foreach i [concat [glob "*"] [glob ".*"]] {

The wishToFront script needs to be installed and run from somewhere
under $GISBASE. It also needs to be arranged such that it doesn't
complain on other platforms.

Also, the 5.7.0 tcltkgrass changes are probably obsolete, as
tcltkgrass has been completely re-written. Most of the functionality
is now provided by libgis. The dialogs which appear in tcltkgrass are
the same ones which you get if you run the command without arguments
or with the --ui switch; tcltkgrass itself is little more than a menu.
