--- Code: ---dir > NUL

Does not error out for me.

See http://en.wikipedia.org/wiki//dev/null

Tim, please read the whole thread. You should test it with "dir > cmd /c NUL"
as this is what $(CMD_NULL) macro expands to, on windows, curently.

(Should expand to plain "NUL" not "cmd /c NUL").

You only stated the issue clearly in this message; I had no idea what you were saying in about 1 in 3 sentences.

Edit: And this does work. So, another possible solution.
"cmd /c > NUL dir"

He's right with his first point, though. I admit that I had difficulties understanding, too, but he's right :)

The other thing (adding sh under Unix) is not necessary, as it works fine with the default shell which is user-configurable.

C::B doesn't have macro for invoking command interpreter. Hence $(CMD) would be usefull.
Pre(post) build steps could benefit from this. And 'sh' is most neutral on non-windowses.
Or it could just yield the value that user has configured in default shell setting.
