I have a user that wants me to check their F2003 code which uses mpif.h.
Attempting to compile with gfortran-4.8.2 -std=f2003 results in errors
coming from mpif.h.  I tried configuring MPICH (v3.1-16-g38a5e61) using
FCFLAGS=-std=f2003, but I get build errors.  GFortran does not have a
-std=gnu2003, so it appears that GNU extensions and F2003+ features are
mutually exclusive.  What is MPICH's intent here?
