Patch from Colin Watson intended to give a clean Unix compile with GCC 4.
[u/mdw/putty] / unix / gtkdlg.c

2 * gtkdlg.c - GTK implementation of the PuTTY configuration box.

6 * TODO when porting to GTK 2.0:
7 *
8 * - GtkTree is apparently deprecated and we should switch to
9 * GtkTreeView instead.
10 * - GtkLabel has a built-in mnemonic scheme, so we should at
11 * least consider switching to that from the current adhockery.
