Comment (by simonmar):
(the patch was a darcs patch, sorry for not mentioning that)
Ok, could you possibly investigate this manually? It's pretty hard to
debug it remotely. To experiment, you can just cut out the test program
from `aclocal.m4` and play with it separately.
Clearly something is not working with `timer_create()` on your system, we
need to figure out what it is, and write a configure test that detects the
problem. One thing you could try is modifying the test to test the
`CLOCK_PROCESS_CPUTIME_ID` timer instead of the `CLOCK_REALTIME` timer,
but you'll need to add a cpu-time-consuming loop into the code.
