Thank you.

That test failure was due to Darwin's definition of the NZERO macro:

    $ grep NZERO /usr/include/sys/param.h
    #define NZERO   0               /* default "nice" */

That conflicts with the POSIX requirement that its value be at least 20:

   XSI           {NZERO}
                     Default process priority.
                     Minimum Acceptable Value: 20

Here's the fix:

        * src/nice.c (NZERO) [NZERO == 0]: Undefine and define to 20,
        to work around the invalid definition from Darwin 7.7.0.
        Test failure reported by Sébastien Maret.
