Hi, For gnulib-tool, it would be useful if 'autoreconf' had an option --no-recurse or --no-recursion or --no-recursive that would avoid recursive self-invocations of autoreconf.
The use case is: gnulib-tool creates many directories with each a Makefile.am and configure.ac and configure file, and on top of that an extra Makefile.am and configure.ac and configure file. When the subdirectories are created, autoreconf is already executed on such a subdirectory. Therefore recursion is not needed. Currently, on a slow machine, "gnulib-tool --create-megatestdir" takes ca. 4 hours of CPU time when using aclocal/autoconf/automake for the top level, and ca. 7-8 hours when using autoreconf. autoreconf is just redoing useless recomputations.
