I'm not really sure if this falls in the same category, but the rule base is a pattern rule... it seems that something like

%.o:%.c | $(intermdiate_path)

intermediate_path is no longer order only, it is instead a valid rule, and that being a directory means it's often newer then the .o in certain filesystems.

in my make 3.80 under linux, $| doesn't have anything, $< is just the .c source file, other things have the intermediate path, but nothing indicates order only, as it would if the order only dependant was specified on a non-pattern rule...

Just a display bug.

The database dump function doesn't make a distinction between the
order-only and "normal" prerequisites.
