+
+ * win32-nat.c (CYGWIN_SIGNAL_STRING): Delete.
+ (_CYGWIN_SIGNAL_STRING): Define if not already defined in cygwin.h.
+ (win32_add_thread): Use XZALLOC rather than xmalloc/memset.
+ (register_loaded_dll): Ditto.
+ (handle_load_dll): Call solib_add here.
+ (handle_unload_dll): Ditto.
+ (info_dll_command): Delete.
+ (handle_output_debug_string): Use official _CYGWIN_SIGNAL_STRING.
+ (win32_current_sos): Duplicate table to pass off to caller rather than
+ deleting our version.
+ (set_win32_aliases): New function.
+ (_initialize_win32_nat): Remove local handling of "info shared". Set
+ deprecated_init_ui_hook to allow late setting of "info dll" alias.
+

* event-top.c (gdb_setup_readline): Don't set gdb_stdout when
