Try to figure out if this is Digital Unix and we need -std1 to get the Sat May 9 20:11:20 1998 Owen Taylor <otaylor@gtk.org> * configure.in (LIBS): Try to figure out if this is Digital Unix and we need -std1 to get the right prototypes. Sat May 9 20:08:12 1998 Owen Taylor <otaylor@gtk.org> * glib/gmem.c: Experimentally restore GMemChunk to its primeval state - where mem areas are freed incrementally instead of searching the tree every time a mem area is completely empty. Also, always keep one mem chunk around. (Reduced calls to malloc() a lot, but doesn't really improve performance significiantly) Fri May 8 21:31:50 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkwidget.c (gtk_widget_queue_draw): Free the draw-queue when we are done. (gtk_widget_queue_draw/_queu_resize): Always return FALSE and avoid having two idles at the same time. Fri May 8 21:04:00 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtktext.c: Various fixes to make sure cache lines are freed if line_start_cache doesn't point to the beginning of the cache.

Reintegrated buffer overflow patches, and added some extra paranoia. Tue May 5 17:04:14 1998 Owen Taylor <otaylor@gtk.org> * gdk/gdk.c (gdk_event_translate): A guint * was being passed where X expected a Keysym *, and keysyms are long's on Alpha Linux. This was causing segfaults in Xlib, apparently because of alignment. (Bug located by Juergen Haas <haas@forwiss.uni-passau.de>) Tue May 5 19:11:27 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkdrawingarea.c (gtk_drawing_area_realize): Always set GDK_EXPOSURE_MASK for DrawingAreas Tue May 5 14:32:37 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkwidget.[ch]: removed gtk_widge_propagate_default_style (superceded by RC file reparsing capabilities) * gtk/gtkwindow.c: Add handling for _GDK_READ_RFCILES client events. (Shouldn't be sent to the InputOnly leader, which it is now by gdk_event_send_clientmessage_toall * gtk/testgtk.c: Added extra button to rcfiles test to send out _GDK_READ_RCFILES events. Tue May 5 11:03:00 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkselection.c (gtk_selection_clear): Fixed reversed conditionals that caused segfault on some platforms. Tue May 5 00:44:47 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkcontainer.c (gtk_container_set_focus_[hv]adjustment): cast to GTK_OBJECT for gtk_object_ref.
