As I described - configure can't compile conftest.c stub
(with the purpose of testing of existance of the library libcomm_err)
because there are unresolved loader references, and as a result:
fatal error:

So how/where your config finds sem_* symbols functions ?
or mebe your libcom_err is self-contained and does not reference them ?

On my fresh Fedora 16 -pthread cc option must be definded
becasue libcom_err is not self-contained and needs sem_* symbols
which option -pthread provides.
