It looks like the Fortran compiler is not correctly preprocessing the 
"udunits.inc" file with the C preprocessor.  It looks like it failed on
the "#define" in that file.

Your options are

    1.  Remove the "#include <udunits.inc>" from the source file, 11.f.
        If you do this, then you will have to declare all the
        UDUNITS functions yourself in the file "11.f".

    2.  See if there's an option to the xlf(1) compiler that will
        ensure that it uses the C preprocessor; or

    3.  Try renaming the input file, 11.f, to "11.F".  Sometimes a
        capital "F" extension gets different behavior from the
        preprocessor.
