[mpich-discuss] Make testing--Failed to build threads

[Dave Goodell]

Are you actually trying to build the threading *tests*?  This code isn't needed to get a working MPI installation…

Otherwise, it looks like your pthreads implementation may not support the pthread_barrier_t type, or perhaps it incompletely supports it in a way that is confusing the configure script (I think we have a fallback for platforms lacking a native pthread barrier).  What platform is this?
