suppressing the newline from echo

I've seen logic in generated configure files to determine how to keep echo
from suppressing the newline (-n, \c, etc).  Some ac_ variables get set
and then used in echo invocations.

Is this available in a macro?  I don't see anything in the 2.13 manual or
the online macro archive[*], and I'm leery of depending on implementation
details like ac_n, ac_c, and whatnot.

[*] Which recently moved; the autoconf homepage needs updating.
