ok, i have a far more specific question about double-colon rules.
it has to do with their use in paul's multi-arch build recipe here:
http://make.paulandlesley.org/multi-arch.html#advanced
part of that makefile are the rules:
Makefile : ;
%.mk :: ;
% :: $(OBJDIR) ; :
and the question is simply, do either of those last two rules
*require* the double colon as opposed to a single colon? i'm not
interested in issues of efficiency, just in absolute requirement.
