Thanks again for the report.
That was caused by a bug in gethrxtime.m4.
The gettime libraries ($LIB_CLOCK_GETTIME) are needed
by gethrxtime.c only if CLOCK_MONOTONIC is *not* defined.

Here's the patch:

2006-08-18  Jim Meyering  <address@hidden>

        * gethrxtime.m4 (gl_PREREQ_GETHRXTIME): Reverse sense of test for
        CLOCK_MONOTONIC.  Otherwise, linking a gethrxtime-using program
        with $(LIB_GETHRXTIME) could fail due to unresolved clock_gettime.
        Reported by Gabor Z. Papp.
