That's interesting because the test has not changed from 1.4.6 to 
1.4.8. Maybe there was some behavior change in hurd in the last 2 
months? If you are interested, you could re-try building 1.4.6-4.

The test is rather weird, anyway. Fortunately, there is a better one 
in apr trunk. Could you give

http://svn.apache.org/viewvc/apr/apr/trunk/configure.in?r1=832904&r2=832903&pathrev=832904&view=patch

a try?

Cheers,
