# because the source directory may already be configured. If you just try
# running configure in a new directory, it complains. For this reason, we move
# config.status out of the way while doing the default configuration. The
# resulting config.h is munged by perl to put #ifdefs round any #defines for
# macros with values, and to #undef all boolean macros such as HAVE_xxx and
