I'm not as familiar with Erlang, so it very well could be that you've
discovered a bug in autoconf.

Because the use of 'echo' is not always portable, so newer autoconf
guarantees a safe fallback (such as printf) in case it has detected that
your shell's echo does not fit autoconf's needs.

It looks like you are reporting a regression that occurred sometime
between 2.60 and 2.62. Could you please check whether 2.63 also has the
bug, so we can fix it?
