2006-10-03 Richard Frith-Macdonald <rfm@gnu.org>
* Source/x11/XWindowBuffer.m: ([_exposeRect:])
Clip draw area to size of buffer rather than size of wiondow,
in case the two have become out of sync somehow.
* Source/win32/WIN32Server.m: Add help key mask
* Source/x11/XGServerEvent.m: ditto
2006-10-02 Nicola Pero <nicola.pero@meta-innovation.com>
* configure.ac: Check the new variable GNUSTEP_IS_FLATTENED,
