add_timeout will now do the callback at time t after the call to
add_timeout, like before.
add_interval_timeout is a new call that measures time from when the
last timeout was called. This has slightly less overhead and allows
accurate spacing of timeouts.
Patch from Stuart Levy so the *last* widget in an Fl_Pack may be
resizable. This should be compatable because resizable didn't do
anything before so there was no reason to set it.
Makefiles for no-cygwin from Paul Baxter (see README.win32 for info).
