+	* gncal.c: Removed #include "gtkcalendar.h", because it now comes
+	from libgnomeui.
+
+	* Makefile.am (gncal_SOURCES): Added new source files to the rules.
+
 	* timeutil.c (format_simple_hour): New function, formats an
 	hour/am_pm pair into a string of the form "3am", "12pm", "05h",
 	"19h", etc.  It is used by the day view widget for its labels.
