OK, thanks. A colleague of mine noticed a bug, in that:

export M4PATH=${AUTO_STABLE}/share/autoconf:${M4PATH}

will set M4PATH to '/foo/share.autoconf:' if it was not previously set, and
an empty path equates to the current directory, which is probably not what
was intended. This really needs a check to see whether M4PATH was previously
set, and only appending to it if so. This isn't an issue for PATH because
you assume it is always set to something.

Cheers,
