 I assume you mean it is a symlink or something similar?
 
 This is interesting because our configure script tries to check for
 sched_yield in -lposix4.  Can you find out why this test fails?  You
 can find the compiler error messages in config.log.

 Hi again.
 I just checked in a change to look for sched_yield in -lrt.
 I checked this in on the 2.95 branch.
 
 Can you try this change?
 Before recompiling, note that you must "rm config.cache"; otherwise
 the cache entry could prevent the new code from running.
 
 Thanks,
 Tom
