Hi John,

Yes, we just got access to an HPUX-10 platform and have discovered that
the -D_HPUX_SOURCE compiler flag is needed to get netCDF to build on
this platform.  This will be made clear in the INSTALL file in the next
release, but for now, try the following:

    1.  Go to the top-level netcdf-3 source directory.

    2.  Execute the command "make clean".

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

    4.  Set the following environment variables to the indicated values:

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

        The "_HPUX_SOURCE" should handle the "EEXIST" problem and the
        "-O3" should mollify the fort77(1) compiler.

    5.  Execute the configure script.

    6.  Execute the command "make".  If this works, try "make test".  If
        the tests succeed, "make install".
