The above message contained the following:

Is the name of the Absoft C compiler "gcc"?

What is the name of

    1.  the Absoft Fortran compiler;
    2.  the Intel C compiler; and
    3.  the Intel Fortran compiler?

The C and Fortran compilers in the "test.log" file that you sent me are
"gcc" and "ifort", respectively.  Does this mean that you used the
Absoft C compiler with the Intel Fortran compiler?  If not, then what
combination did you use?

The Intel Fortran compiler uses the same calling conventions as the
Portland Group Fortran compiler.  The "cfortran.h" file that you sent
basically uses the "pgiFortran" definitions -- so it should work for the
Intel Fortran compiler.

Alternatively, when using the Intel Fortran compiler, you can use the
"cfortran.h" file that comes with the distribution if the environment
variable CPPFLAGS defines the C macro "pgiFortran" before the configure
script is executed, e.g.,

    export CPPFLAGS="-DpgiFortran"
    ./configure ...

Also, when using the Intel Fortran compiler, try setting the following
environment variables to the indicated values before executing the
configure script:

    export FLIBS="-L/opt/intel/compiler70/ia32/lib -lPEPCF90"
    FFLAGS="-O -mp"

You might have to adjust the pathname in the FLIBS variable.  The "-mp"
option is NECESSARY to obtain a successful "make test".

When using the Absoft Fortran compiler, try defining the C macro
"AbsoftProFortran" (rather than "AbsoftUNIXFortran") before executing
the configure script, e.g.,

    export CPPFLAGS="-DAbsoftProFortran"
    ./configure ...
