2001-10-06 Richard Frith-Macdonald <rfm@gnu.org>
* Source/NSConnection.m: Increase default timeouts to max value.
Improve algorithm for polling for messages when waiting for a reply
in multithreaded mode ... use fibonacci sequence for delays rather
than doubling each time.
* Headers/Foundation/NSConnection.h: Remove default timeout constant.
* configure.in: Check for float.h, not for values.h

* NSTimeZones/NSTimeZones.tar: Updated to latest info. * NSTimeZones/NSTimeZones.tar: Updated to latest info.
