host_name and target_name

[Andrew Cagney <ac131313@cygnus.com>]

Hello,

I recently changed the type of ``host_name'' and ``target_name'' to
(const char *) since they are not modified.  Unfortunatly, Tcl_SetVar2()
expects a non-const value parameter even though it does treat it as
const/read-only.

The patch below casts those parameters.  Perhaphs this should be
converted into a bug-report for the TCL group.

	* gdbtk.c (gdbtk_init): Cast ``host_name'' and ``target_name'' to
 	void.  While Tcl_SetVar2 treats the value argument as read-only
	its prototype does not specify const for the parameter.
