+
+ * 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.
+ * gdbtk.tcl: New view option to disable line numbers. Put catch
+ around most uses of gdb_cmd. Add update button to reg config
+ window. Stop doing immediate updates when selecting registers.
+ Change register view values into checkbuttons.
