2002-08-25 Stephane Carrez <stcarrez@nerim.fr>
+ * tuiStack.c (tuiSetLocatorContent): Remove.
+ (tuiUpdateLocatorInfoFromFrame): Remove.
+ (tui_set_locator_info): Allocate the content buffer if necessary.
+ (tui_set_locator_filename): Call tui_set_locator_info directly.
+ (tuiShowFrameInfo): Likewise and use find_pc_line instead of
+ find_pc_symtab.

+
* tuiSourceWin.c (tuiDisplayMainFunction): Update to use
tuiUpdateLocatorFilename.
* tuiStack.c (tuiSetLocatorInfo): Make it static.
