You're thinking of automake, not autoconf.
Automake ships every version from 1.4 to 1.10, and has an alternatives
wrapper to let you select a default as well as a script to ensure the same
version is picked to regenerate any Makefile.in as was previously used.
Autoconf ships only one version each of 2.1 and 2.5 series, currently
2.13-5 and 2.63-1, and has a wrapper script, but it only helps hide the
differences in version number within a series. You can specify
WANT_AUTOCONF=2.5 and it will select whichever one of 2.59 to 2.63 you have
installed, but you only have one of those installed.

No, you really do need it, either by rolling back your install, maybe using
the Cygwin Time Machine, or by building it from source.
