Maybe a command line switch to ignore it would be in >order? Defaulting, of course, to POSIX. POSIX says that anything after <TAB> must be passed to shell exactly. It says nothing about error here. So, simple <TAB> it is equal to sh -c "" Normal make must skip such lines. F.e. GNU makes which claims itself as POSIX-conformant don't produce error here. BSD make isn't POSIX make, differences are too big, but even in this case as long time tradition of BSD make such lines was accepted without error. As I notice, this nitpicking change (producing error) cause too many ports Makefiles to be converted. I vote for removing this superflows checking. - -- Andrey A.
