96# @FUNCTION: eautoreconf
97# @DESCRIPTION:
98# This function mimes the behavior of autoreconf, but uses the different

100# the directory with include files can be specified with AT_M4DIR variable.
8# 101#
9# This eclass was made to bridge the incompadibility problem of autoconf-2.13, 102# Should do a full autoreconf - normally what most people will be interested in.
10# autoconf-2.5x and automake-1.4x, automake-1.5x. Most packages needs 103# Also should handle additional directories specified by AC_CONFIG_SUBDIRS.
11# autoconf-2.13 and automake-1.4x, but cannot work with the latest versions 104eautoreconf() {
12# of these packages due to incompadibility, thus when we have a package that 105 local x auxdir g
13# needs the latest versions of automake and autoconf, it begins to get a
14# problem.
