	* */*.[hc] */*/*.c : a bunch of changes to make Dia compile with
	-std=c89. Mostly //-comments and M_PI -> G_PI
	[Istar, Jackson, KAOS were removed from build cause they
	simply have *too* much C++ comments ;]
	* object/UML/association.c : use g_strdup() not plain strdup()
	* app/paginate_psprint.c : avoid storage size of `pipe_action'
	isn't known with more portable signal code

	* app/app_procs.c : don't call gtk_init() if just --version
	is requested (bug #144321, Vladimir Kondratiev)

	* lib/prop_attr.c(fontprop_set_from_offset) : only unref
	DiaFont* if not NULL
	* objects/UML/class.c : moved fill_in_fontdata() to
	umlclass_load() to avoid such trouble, though unsure if
	this really is an improvement...

	* shapes/network/makefile.am : patch-panel added here too
