# Now add new directories.

# 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.

# First we add a new directory by modifying configure.in directly.
# We update configure.in *before* updating sub/Makefile.am; subdir8.test
# does it in the other way: it updates confiles.m4 (which is m4_included
# by configure.in there) after Makefile.am.
