This # definition is slower than the version in Autoconf 2.64, because it # can only use interfaces that existed since 2.59; but it achieves the # same effect. Quoting is necessary to avoid confusing Automake. m4_version_prereq([2.63.263], [], [m4_define([AC][_DEFUN_ONCE], [AC][_DEFUN([$1], [AC_REQUIRE([_gl_DEFUN_ONCE([$1])], [m4_indir([_gl_DEFUN_ONCE([$1])])])])]dnl [AC][_DEFUN([_gl_DEFUN_ONCE([$1])], [$2])])]) # gl_00GNULIB # ----------- # Witness macro that this file has been included.
