Gcc requires that an unpatched, pristine version of autoconf be used when preparing patches for official submission. For various reasons [1] these pristine versions cannot coexist with the existing autoconf packages in /usr.
gcc-4.3.x and gcc-4.4.x development requires autoconf-2.59 gcc-4.5.x thru gcc-4.8.x development requires autoconf-2.64 This package provides autoconf-2.64 and installs into /opt/gcc-tools/epoch2/{bin,share} for use when developing gcc-4.5.x, 4.6.x, 4.7.x, and 4.8.x. For more information about these new *-epochN packages, see http://cygwin.com/ml/cygwin-announce/2010-01/msg00007.html http://cygwin.com/ml/cygwin-announce/2010-01/msg00008.html Autoconf is an extensible package of m4 macros that produce shell scripts to automatically configure software source code packages.
