Hi there,

continuing my make adventure, I've stumbled across the following
inconsistency. I would even call it a bug.

In any event, could someone point me to a place in the make(1) man page
where it says that the S and C modifiers dereference variables given in
both the pattern and replacement, while the N and M modifiers insist on
being fed literal strings? I couldn't find it. Thanks! :)

ignore your message.
