@ocaisa Can you double-check whether -fopenmp is supported properly by the oldest Intel compilers we employ (v11.x)?

Other than that, good to go, thanks for looking into this!

@boegel I don't have access to sources for v11.x and there's nothing in the documentation I could find about -fopenmp so I can't be sure either way

@ocaisa I gave it a test myself, -fopenmp doesn't work with Intel 11.x...

$ icc --version

$ icc -fopenmp omp_hello.c -o omp_hello
icc: command line warning #10006: ignoring unknown option '-fopenmp'
omp_hello.c(22): warning #161: unrecognized #pragma
  #pragma omp parallel private(nthreads, tid)
          ^
/tmp/iccRDDbxa.o: In function `main':
omp_hello.c:(.text+0x27): undefined reference to `omp_get_thread_num'
omp_hello.c:(.text+0x40): undefined reference to `omp_get_num_threads'

It seems to be OK in v12.x though...

I don't want to spend too much effort on making sure things still work with 11.x, but since we haven't officially deprecated that yet, we should take it into account.

I'll take a look on how to do that in a non-intrusive way; it's not straight-forward since here it's being defined as a part of a constant...
