While bootstrapping Bison I noticed that gnulib-tool assumes Autoconf versions 2.57 through 2.59. But Bison assumes 2.60. On the theory that gnulib-tool should assume the latest stable version, and you can copy onceonly by hand if you want an earlier one, I installed this:
2006-07-08 Paul Eggert <[EMAIL PROTECTED]> * gnulib-tool (func_get_filelist): Don't echo m4/onceonly_2_57.m4, for the benefit of people using Autoconf 2.60. If you want to support older Autoconf versions you can copy m4/onceonly_2_57.m4 (or m4/onceonly.m4, if pre-2.57) manually. --- gnulib-tool 23 Jun 2006 19:27:17 -0000 1.113 +++ gnulib-tool 9 Jul 2006 03:29:48 -0000 @@ -548,7 +548,7 @@ func_get_filelist () { sed -n -e "/^Files$sed_extract_prog" < "$gnulib_dir/modules/$1" #echo m4/onceonly.m4 - echo m4/onceonly_2_57.m4 + #echo m4/onceonly_2_57.m4 } # func_get_dependencies module @@ -1813,7 +1813,7 @@ case $mode in ;; import | update ) - + # Where to import. if test -z "$destdir"; then destdir=.
