We don't have access to a FreeBSD system, so thank you for sending this
in.  I'm slightly surprised that the FreeBSD m4(1) utility doesn't handle 
the "-B10000" option because the BSD/OS m4(1) utility does.

The best approach would be to tell us the environment variable settings
that you used to build the package -- we could then incorporate those
settings in the EXAMPLES section of the INSTALL file.  What should the
settings be for the following:

    ENVIRONMENT VARIABLE        MEANING                 EXAMPLE
    --------------------        -------                 -------
    CC                          C compiler              /usr/bin/gcc
    CPPFLAGS                    C preprocessor flags    -DNDEBUG -Df2cFortran 
    CFLAGS                      C flags                 -O
    FC                          Fortran compiler        /usr/local/bin/fort77
    FFLAGS                      Fortran flags           -O -w -Nx400
    CXX                         C++ compiler            /usr/bin/g++
    M4                          m4 preprocessor         /usr/bin/gm4
    M4FLAGS                     m4 flags                -B10000

Would the above settings work?  (Obviously, the M4FLAGS setting
wouldn't.)  What are the actual, absolute pathnames for your gcc,
fort77, g++, and m4 utilities?
