I bet -lrt has to be linked in as sem_* are part of the real time extensions of
POSIX.

I believe that you would win that bet:

------- Comment #4 from roger at eyesopen dot com 2006-02-08 17:46 -------
This problem affects both hppa*-hp-hpux* and ia64-hp-hpux*. It appears that
the required sem_init, sem_wait, sem_post, etc... symbols are defined both in
the -lrt libraries on HPUX and in the -lc_r libraries. The fix is to update
LIB_SPEC, perhaps in the -pthread clause, for HPUX, but I'm not sure if it
requires adding -lrt or changing -lc to -lc_r, or adding -lc_r? I notice that
config/pa/pa-hpux10.h does mention -lc_r, but for use with -threads.
Should -pthread pull in the required symbols? i.e. is this a libgomp problem
or a target problem?

I'm not 100% certain but I believe libc_r needs to be used with dce
threads, and librt with posix threads. HP-UX 10 doesn't have the latter.
We only support posix threads on hppa*-hp-hpux11*.

Although it's relatively easy to change LIB_SPEC, I'd like to keep the
number of libraries that are linked against to a minimum.
