Sure, the question was more about whether the system call exists
everywhere.

I can add HPUX 10.20, Mac OS X 10.2.3, and a pretty ancient Linux
(kernel 2.0.36, not sure of the exact distro) to the list of stuff
your test program seems to pass on.

My feeling is we may as well put it in. If it turns out we have
platforms without utimes(), we can put in a configure test and #ifdef
it. If the call doesn't exist or doesn't update the mod time as
expected, we're no worse off than before --- and for platforms where
it does work, this is a big win.
Thanks for looking into it! I'll work on applying the fix.
