That's why I proposed (exit $?) instead, if status-preservation would be
an important consideration in the AS_NOP implementation :)  However, there
are no places in autoconf where such a nop exist, to my knowledge (which
is quite superficial in great areas of autoconf though), and I doubt there
really is a need for it.

Hmm, I just wanted to bring it up for discussion - but I see now that I
the thread is in autoconf-patches.  I changed list to autoconf instead.
To any new readers, the question is whether creating macros named AS_NOP,
AS_TRUE, and AS_FALSE will make autoconf macros more readable....
