Such an FD is too low level a detail to be left to the user. We try
to publish high level interface, and keep low level private to
Autoconf, so that we can adjust Autoconf to future needs.

The internal detail AC_FD_CC no longer exists, and is replaced with
the internal detail AS_MESSAGE_LOG_FD. As an internal detail, an
internal AU_ALIAS preserve some backward compatibility with the
internal detail AC_FD_CC.
