Sorry, I didn't check properly.

I had no idea this was a wrapper, and I thought it was just the
Debian alternative system selecting either of the too, and I'm
using to having 2.59 as the default version.

Looking at the wrapper, I see:
if (defined ($infile)) {
    # Assume an input file ending in .ac is 2.50,
    # because that extension was introduced after 2.13.
    if ($infile =~ /\.ac$/) {
        ac250 ();
    }

You get this behaviour on Debian if you install both autoconf2.13
and autoconf at the same time.

The wrapper seems to be part of the autoconf2.13 package, which
is 2.13-55, and I have autoconf 2.59a-7.
