Question about the fortran stuff in opal/util/arch.c...

I see the following comment:

** The fortran integer is dismissed here, since there is no

You can tell the intel compiler (and maybe others?) to compile fortran
with double-sized integers and reals. Are we disregarding this?
I.e., does this make this portion of the datatype heterogeneity
detection incorrect?
