Akim, Now that you seem to be at revamping autoreconf's options, just a feature request:
Would it be possible to change autoreconf to * not recurse it into CONFIG_SUBDIRS by default * to let it recurse only into CONFIG_SUBDIRS if a --recursive option was specified. (What I have in mind is a similar behavior as to chown -R). Reasonale: Running autoreconf inside of deep sourcetrees with several levels of CONFIG_SUBDIRS currently always (and often unnecessarily) rebuilds all CONFIG_SUBDIRS from all subdirs. Ralf
