	* libgimpcolor/Makefile.am
	* libgimpmath/Makefile.am: use GLIB_CFLAGS instead of GTK_CFLAGS.

	* app/libgimp_glue.[ch]: do not allow anyone but app/libgimp_glue.c
	to include libgimp_glue.h.

	* libgimpbase/gimpunit.h
	* libgimp/gimpunit.c: cache return values of GimpUnit PDB calls and
	return const strings from the GimpUnit accessor functions just like
	the equivalent functions in the application do.

	* plug-ins/common/uniteditor.c: don't free GimpUnit strings. Don't
	free the result of gtk_entry_get_text() neither.
