In order to avoid the above problem, you must define the C macro that
tells the C compiler what Fortran calling-conventions to use (the buid
procedure builds a Fortran interface as well as a C interface).  If you
know what Fortran compiler you want to support, then you should define
the corresponding C macro from the list above (e.g., "NAGf90Fortran" for
the Absoft UNIX F77 compier).  If you don't care about Fortran support,
then any of the above C macros will do.

You'll have to start from scratch in order for the C macro definition to
"take".  Do the following:

    1.  Go to the top-level source-directory.

    2.  Perform steps 3 through 5, described near the end of the file
        INSTALL.

    3.  Ensure that the CPPFLAGS environment variable defines an
        appropriate C macro, e.g.,

            export CPPFLAGS='-Df2cFortran -DNDEBUG'

    4.  Perform steps 6 through 9, described near the end of the file
        INSTALL.

Please let me know if this helps.
