The last line above indicates that the configure script thinks that
you're attempting to cross-compile.  It shouldn't think this and I'm not
surprised that the build fails from this point on.

We have to determine why the configure script thinks you're
cross-compiling.  Try the following:

    1.  Go to the top-level source directory.

    2.  Execute the command `make clean' (this might not work because
        the makefiles might not exist -- don't worry about it).

    3.  Remove the file `config.cache'

    4.  Echo the the variable $cross_compiling.  If it's set to `yes',
        then that's the problem.  Unset the variable.

    5.  Edit the file `configure'.  Find the line that contains the string
        `checking whether cross-compiling'.  Insert the command `set -x' 
        before that line and the command `set +x' before the later line that
        contains the string `checking size of int'.

    6.  Execute the configure script.  Trap the output and send it to
        me.

I think there's something in your environment that's causing the
configure script to think that you're cross-compiling.  I don't think
this is strictly a UNICOS 9.0 issue.
