New Revision: 7686

Modified:
   mpich2/trunk/src/mpi/init/init.c
Log:
only create storage for MPIR_async_thread_initialized in libmpich.a

Prevents duplicate storage on platforms like darwin that don't support
weak symbols and therefore have two libraries in order to support the
PMPI profiling interface.  Previously, there was also a copy in
libpmpich.a, which contains the actual "MPI_" versions of the routines.

No reviewer.
