Is there something wrong with our supplied autconf2.1 package?

This is a regression in cygport, which I'll see about fixing.

(Briefly: cygport tries to detect the version of autoconf which was used 
to generate the ./configure script, so it knows what option arguments to 
supply to it.  Recently this was extended to detect autoconf 2.7x, but 
that seems to have broken detecting autoconf 2.1x)

I'm not sure why this change is needed.
