Starting with SDL version 1.2.14, caps lock and num lock keys
will send a SDL_KEYUP when SDL_DISABLE_LOCK_KEYS=1 is set in
the environment.
The new code sets the environment unconditionally
(it won't harm old versions which do not know it).
The workaround for SDL_KEYUP is only compiled with old SDL versions.
A similar patch without handling of old SDL versions was already
published by Benjamin Drung for Ubuntu.
