You might try the settings recommended in the INSTALL file for HP-UX
B10.20 systems:

    CC=c89
    CPPFLAGS="-D_HPUX_SOURCE -DNDEBUG"
    CFLAGS=-O
    FC=fort77
    FFLAGS="-O3 -w"
    CXX=CC

They worked for us.

To use the above, do the following:

    1.  Go to the top-level source directory,

    2.  Execute the command "make distclean".

    3.  Remove the file "config.cache" if it exists.

    4.  Set the above environment variables.

    5.  Execute the "configure" script.  Redirect standard output and
        standard error to the file "configure.log".  If an error message
        occurs in the output, then stop and send me the files
        "configure.log" and "config.log".

    6.  Execute the command "make".  Redirect standard output and
        standard error to the file "make.log".  If an error occurs,
        then stop and send me the files "make.log" and "configure.log".

    7.  Execute the command "make test".  Redirect standard output and
        standard error to the file "test.log".  If an error occurs,
        then stop and send me the files "test.log", "make.log" and
        "configure.log".

    8.  Execute the command "make install".  Redirect standard output and
        standard error to the file "install.log".  If an error occurs,
        then stop and send me the files "install.log", "test.log",
        "make.log" and "configure.log".

Please let me know if this helps.
