When compiling using the mpif90, mpicc and mpicxx commands, the compiler spews out warnings that the "-pthreads" option is deprecated and that "-reentrant threads" should be used instead. While this is not a problem per se (yet), it confuses our users. I tried to fix this, but the settings are configured quite deep in some autoconf macros, and I decided to leave it for the time being.

Ahh, that's a useful workaround! But it would be nice to have a solution
which works automagically with both gcc and intel, i.e. when using
OMPI_CC=icc. But for now I can ajust the flags for the intel users, and
avoid confusion :)
