+
+ * gdbtk.c (gdbtk_wait gdbtk_init): Use different method of
+ enabling I/O interrupts for SVR4 (streams).
+ * (start_saving_output save_output get_saved_output
+ finish_saving_output flush_holdbuf gdbtk_flush gdbtk_fputs
+ gdbtk_init):
+ Totally revamp to use TCLs dynamic string functions. Also, quote
+ all data passed back to TCL to prevent errors with unmatched
+ braces, odd characters, etc... This fixes several wierd problems
+ with outputting strings containing unmatched braces.
+ * (breakpoint_notify gdb_loc): Use long hex format to output
+ addresses of breakpoints and PCs. This fixes some Alpha problems.
+ * (breakpoint_notify): Add stream arg to call to gdbtk_fputs.
+ * (gdb_listfiles): Also, go through the symtabs when looking for
+ files. This makes xcoff work (sort of), but probably breaks
+ something else.
+ * (gdb_stop): Return TCL_OK instead of nothing. This fixes odd
+ TCL errors when hitting stop button.
+ * (tk_command): Don't pass interp->result on to Tcl_{Var}Eval, as
+ that will trash the result. strdup the result instead and pass
+ that on. Improve error handling as well.
+
+ * gdbtk.tcl (gdbtk_tcl_flush): Use global def of
+ current_output_win. Makes flushing actually work!
+ * (asm_win_name create_asm_win update_assembly): Bunch of fixes
+ to make assembly windows stop flashing when loading a new file.
+ * (gdbtk_tcl_busy gdbtk_tcl_idle): Use catch to prevent gdb_cmd
+ errors from losing control.
+ * (create_source_window): Add source file selection to View menu.
+ * (create_command_window (<Key-Return> binding): Quote text fed
+ into gdb_cmd to prevent eval errors.
