-       * defs.h, gdbtk.c (gdbtk_fputs), main.c (gdb_fputs), top.c:  Add stream arg
-       to fputs_unfiltered_hook.  Differentiate stdout from stderr when
-       passing text into tcl land.
-       * defs.h, top.c, utils.c (error):  Add error_hook.
-       * gdbtk.c:  Improve mechanism for capturing output values.
-       * (full_filename):  Remove.
-       * (gdb_cmd call_wrapper gdbtk_init):  Protect all calls from tcl
-       land with call_wrapper.  This prevents longjmps (usually via
-       error()) from jumping out of tcl/tk and leaving things in an
-       indeterminate state.
