Re: Should libXt-devel be required to build Emacs?

[Richard Stallman]

    There's a problem with this: Autoconf 2.61 was only released in
    November this year, and it requires a new version of M4 (1.4.8), which
    in turn requires a new libc6.  Most existing GNU/Linux distributions
    won't have these packages (at least in their "stable" branches).

That's not so bad.  Most users don't need to rebuild the configure
file, so they won't have a problem.

However, we could ask the Autoconf developers to release a patched
version 2.59.1 which fixes this bug and doesn't require a new M4.
