Ok, then I'm in favor of LT_LANG([language tag as defined by
autoconf]) but against the proposed new options to LT_INIT. If there
is no LT_LANG, language tags should be inferred by configure.ac, else
defined explicitly by LT_LANG. This still leaves the libtool bootstrap
issue unsolved but I say create a private macro (_LT_xxx) to solve the
bootstrap issue.
