# We don't recurse into the library packages with autoreconf anymore,
# so we have to do this manually. To avoid a strict dependency on
# autoreconf, we are careful to call autoreconf only when configure
# does not exist yet or the corresponding configure.ac/aclocal.m4 is
# newer. This would be dead easy if every shell supported the "-nt"
# option for "test", but this is not the case. The only portable
# solution seems to be via find's "-newer" option or to basically give
# up and replace find with perl: :-P
