Changes 1.6.1:
	The gl_event_handler() function had the endif of a
	conditional compilation clause in the wrong place. This
	only upset the compiler on unusual systems that don't
	have select(). The problem was seen under Mac OS X, due
	to the configuration problem in 1.6.0 that caused the
	configure script to mistakenly report that select wasn't
	available.
