GNU Autoconf is an extensible package of m4 macros that produce shell
scripts to automatically configure software source code packages. These
scripts can adapt the packages to many kinds of UNIX-like systems
without manual user intervention.  Autoconf creates a configuration
script for a package from a template file that lists the operating
system features that the package can use, in the form of m4 macro calls.

Multiple versions of Autoconf can be installed at the same time --
the autoconf wrapper choses among them.

Cygwin Packaging Notes

Autoconf upstream has stated that the 2.7x releases are not fully
backwards compatible.  Cygwin therefore chose to provide a new
autoconf2.7 package (keeping autoconf2.5 available) and modifying the
wrapper script to allow packaging systems to set WANT_AUTOCONF=2.7 to
select a newer autoconf version.  The default (when no explicit
WANT_AUTOCONF is set) is still "2.5", which selects autoconf version
2.69 on Cygwin.  The default will change to "2.7" after some period of

Cygwin package maintainers are encouraged to set WANT_AUTOCONF=2.7 in
their cygport configuration or in individual cygport files in order to
check for regressions.
