* glib.h: typedef gint gboolean;
this is needed to provide portability with big-endian platforms (e.g.
try sizeof(bool) for c++ on big-endians - it's 4).
this is also needed to maintain some_union.d_gint==some_union.d_gboolean.
plus, gint to gboolean casts and vice versa need to be possible without
loss.
Thu May 14 03:04:43 1998 Tim Janik <timj@gtk.org>
* gtk/gtktypeutils.c (gtk_type_free): new function to take care about
freeing types.
(gtk_type_set_chunk_alloc): new function to allow allocation of new
types from a mem_chunk of certain size (n_chunks==0 indicates allocation
thorugh g_malloc).
* gtk/gtkobject.c (gtk_object_finalize): free an object through
gtk_type_free().
* gtk/gtkbutton.c (gtk_button_get_type): set chunk preallocation for
GtkButtons to 16.
* gtk/gtkmenuitem.c (gtk_menu_item_get_type): likewise (16).
* gtk/gtklabel.c (gtk_label_get_type): likewise (32).
