There are two warnings that are big offenders. First is the "unused variable" warning due to a static assert. I asked for help with it at https://gcc.gnu.org/ml/gcc-help/2015-07/msg00070.html. Second is the "unknown pragma" warning. Here's part of the problem, but I don't expect much to come of it: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=53431. Here's another piece of the same problem: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66943. I really don't understand the 66942 warning since GCC is an OpenMP conforming compiler. '#pragma omp' is known to it in all configurations. The only thing that changes is OMP is "active" when '-fopenmp' is passed on the command line. Jeff
