        * Makefile.in: Add GDBTK_CFLAGS - this is now used to hold
        -fwritable-strings when compiling with Tk8.1.
        * configure.in: Add GDBTK_CFLAGS, set it to -fwritable-strings for
        Tcl/Tk8.1 & greater.
        * acinclude.m4: Move the rest of the defines to find Itcl, Itk &
        Tix from aclocal.m4 to here.
        * aclocal.m4: regenerate.
        * configure: regenerate.

        * gdbtk-hooks.c (x_event): Tcl_ObjGetVar2 was removed from
        Tcl8.1.  Use Tcl_GetVar2 instead.
        * gdbtk-hooks.c (gdbtk_trace_find): Fix up call to
        Tcl_GlobalEvalObj for Tcl/Tk 8.1.
        * gdbtk-hooks.c (gdbtk_trace_start_stop): Call to Tcl_EvalObj was
        inefficient, replace with call to Tcl_GlobalEval.
        * gdbtk.c: Don't swap out the Tcl_Alloc calls in gdbtk.c.  We took
        care of that in Tcl itself for 8.1.
        * gdbtk.c: Remove const from the script string since Tcl8.1 has
        taken to scribbling sentinals into strings passed to it again...

        * gdbtk-cmds.c (wrapped_call): Change declaration of 1st arg from
        char * to PTR to eliminate warning.
        * gdbtk-cmds.c (perror_with_name_wrapper): Ditto
