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 <[EMAIL PROTECTED]>
* 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.
