	* configure.in: Added a conditional definition of the preprocessor
	symbol GIMP_UNSTABLE if the autoconf symbol GIMP_UNSTABLE is
	defined.

	* app/errors.c (gimp_errors_init): Replaced the #if test on
	GIMP_MINOR_VERSION modulo 2 by #ifdef GIMP_UNSTABLE.

	* app/composite/gimp-composite.c (gimp_composite_init): Print the
	init messages only in unstable versions.  Split the messages in
	two lines and mention "supported by gimp_composite" in order to
	give a hint that the availability of some features depends also on
	what code has been written.  Fixes bug #128825.
