i've just checked on Solaris 11 express:
both /usr/gnu/bin/cp [cp (GNU coreutils) 8.5] and /usr/bin/touch -r seem
to support nano-second timestamps.

hmmm... this could work around the problem, but kind of interferes with
our goal of a read-only source directory  :)

perhaps just installing new GNU coreutils on systems where this problem
occurs is the way to go...
