The version.m4 file gets updated first, then 3 sets of "touches" happen
with a 1 second sleep between them.  After that I run autoreconf.

Using the actual filenames now, after a repo update but before running
the "bootstrap" script:

address@hidden ls -l config.h.in aclocal.m4 sntp/m4/version.m4
-rw-rw-r--  1 harlan  staff  41166 Feb  4 21:40 aclocal.m4
-rw-rw-r--  1 harlan  wheel  41299 Jan 28 02:07 config.h.in
-rw-rw-r--  1 harlan  wheel     40 Feb 21 23:20 sntp/m4/version.m4
address@hidden ./bootstrap
...
address@hidden ls -lT config.h.in aclocal.m4 sntp/m4/version.m4
-rw-rw-r--  1 harlan  staff  41166 Feb 23 15:10:10 2014 aclocal.m4
-rw-rw-r--  1 harlan  wheel  41378 Feb 23 15:10:30 2014 config.h.in
-rw-rw-r--  1 harlan  wheel     40 Feb 23 15:10:03 2014 sntp/m4/version.m4
address@hidden

... and *this* time it didn't rebuild the top-level config.in.h .

I'm about to roll another release; I'll try again after that's done and
include the 2nd instance of config.h.in in the list (we have a nested
project, too).
