I submitted this patch twice to gtk-devel-list, and received no comments, so
am committing it. Although not exhaustively tested, I have been using this
gtk+ for a week w/o problems, and I did read the code to ensure that nothing
ever writes to these data structures. If by chance people encounter SEGV's in
gtk+ code that is setting values in global data structures, this patch could
be a possible culprit.
1998-11-30 Elliot Lee <sopwith@cuc.ml.org>
* {gdk,gtk}/*.c: Make read-only data structures "static const" to
allow them to be shared, mainly including (but not limited to) the
GtkTypeInfo structures for each class.
* gtk/gtkfilesel.c: Add /net to the "leave me alone" directory listing.
