	* glib/gmain.c: Improve debugging printouts. When
	G_MAIN_POLL_DEBUG is defined, we check for an environment variable
	of the same name to decide whether to print out debugging
	information or not. G_MAIN_POLL_DEBUG is always defined on Windows
	as there is more often a need to debug this stuff there. On Unix
	the definition has to be uncommented (or done on the compile
	command line).
