As I said, I haven't looked at it in any detail, but it seems that
autoconf is already multi-version, so I guess it would be possible to
introduce an autoconf2.7 package in addition to the existing two.
That's a slightly wonky way to do that when we expect to later on just
replace 2.69 with 2.71, though.

The check is in autotools.cygclass (with an obvious fix that you can
apply directly in the installed file):
https://cygwin.com/git/?p=cygwin-apps/cygport.git;a=blob;f=cygclass/autotools.cygclass;hb=336c67d359d7676216bc2e29fe304819505cdba0#l398

If you just removed that line it won't use the new autotools and run
with whatever Tcl was shipped with.
