114# the directory with include files can be specified with AT_M4DIR variable.

11# autoconf-2.13 and automake-1.4x, but cannot work with the latest versions 118eautoreconf() {
12# of these packages due to incompadibility, thus when we have a package that 119 local x auxdir g
13# needs the latest versions of automake and autoconf, it begins to get a
14# problem.
