# We shouldn't need to $sleep here: configure ensures that files
# generated by it are newer than configure.  Thus, even if
# Makefile.in is newer than configure but the updated Makefile.am
# below has the same timestamp as Makefile.in, the latter should
# be rebuilt due to its dependency on configure.in.

# The first step users typically do when adding a new subdir is
# editing configure.in.  That is already tested by subdir5.test,
# though, so here we try to just edit a file that is included by
# configure.in, without touching configure.in itself.
