What is the recommended way to check to see if OpenMP is supported
from within a configure script? I am already using AC_OPENMP([C]) but
it does not actually check for OpenMP. All it verifies is that a
compiler option is selected which does not result in an error, or
create an output file. This makes AC_OPENMP not terribly useful other
than possibly enabling the functionality.
If there is a way to check to see that _OPENMP is defined after CFLAGS
has been updated, then that would be a positive check. How can I
easily do that?
