I just had an idea:

On Unix systems, "ln -s `which wish` $GISBASE/bin/grasswish".
Any desired wish could be used, configure could take a 
--with-wish=/path/to/mywish argument for configurability, 
or check for "wish, wish8.0, etc." for known working versions.

On WinXX systems, The tcl-restart hack doesn't work anyway,
and you have to either type "wish /path/to/tcltkgrass", or
even better, create a tcltkgrass.bat file that does the same 
thing, i.e. "wish /path/to/tcltkgrass %1 %2 %3 %4 ... %9".

This way, the user can update their wish, and grass doesn't 
necessarily rely on a particular version of wish, just a link
from (or copy in) $GISBASE/bin/grasswish to the "real" wish.
