commit de7601f149a5fedc1f3f62c62ba94b9d0e3d2069
Author: Paul Eggert <address@hidden>
Commit: Paul Eggert <address@hidden>
Port to GTK with strict C11 compiler
* src/gtkutil.c (xg_create_frame_widgets, xg_toggle_notify_cb):
Cast from function type to void * where the C standard requires this.
This works around a problem in the prototypes for
g_signal_handler_find and g_signal_handlers_block_by_func, which
use gpointer instead of GCallback. Found by using gcc -pedantic.
