Fortran logical fix.

I don't have a testcase for this, I just found the bug while inspecting
OMPI's use of OMPI_FORTRAN_VALUE_TRUE. The following line:
   if (OMPI_FORTRAN_VALUE_TRUE == *flag) ...
is okay in the model where users build a whole new
OMPI depending on what fortran compiler they're using. But for a general
purpose build, it requires OMPI_LOGICAL_2_INT(), which
converts the incoming fortran-logical to 0 or 1 for C, eg
    if (1 == OMPI_LOGICAL_2_INT(*flag)) ...
