It's not a glich. POSIX doesn't require echo to support -n. It's
very commonly supported, but not required. Darwin (well, OSX) is
POSIX compliant, and chooses to not support -n.
The gotcha is that configure (from autoconf) runs via /bin/sh, and
cat > echotest.sh
echo -n foo
$ sh echotest.sh
$ bash echotest.sh
Optional, but legal behavior.
