[project @ 2005-02-10 04:58:09 by wolfgang]
Add a special case for Mac OS X to FP_PROG_AR_NEEDS_RANLIB.
On Mac OS X, we need to run ranlib after installing .a files because
they contain a timestamp which will be outdated after installing.

We could do a proper test for that, but it would contain the command
'sleep 6' and still apply only to one platform.
