Hello Jim.

Just a minor nit, since your fix will have to be ported to automake's
`tests/defs' too ...

Wouldn't it be simpler, and potentially more correct, to use simply:

 warn_ () { eval 'echo "$@" 1>&'"$stderr_fileno_"; }

With your new implementation, I see this on Debian with bash and dash:

 $ stderr_fileno_=2; warn_ () { eval 'echo "'"$@"'" 1>&'"$stderr_fileno_"; }
 $ $ warn_ '$HOME'
 /home/stefano

which is not intended behaviour IMHO.
