	* configure.in: Dont complain, if --without-threads or
	--with-threads=none is supplied; Test for pthread_attr_init
	instead of pthread_cond_init, if threads seems to be supported by
	standard glib. (CFLAGS): Use G_THREAD_CFLAGS for compiling of glib
	as well.

	* glib.h, gmutex.c: Changed private to private_key to avoid
	problems when compiling with under C++.
