Why not 2.9.9?  If you are using 2.9.x, you might as well use the
latest one.

| Octave is now configured for i686-pc-linux-gnu

Run configure like this:

  configure CPPFLAGS="-I$HOME/tmp/SuiteSparse/UMFPACK/Include" \
            LDFLAGS="-L$HOME/tmp/SuiteSparse/UMFPACK/Lib" \
            ... other otptions ...

This way, the options will be recorded in config.status, you won't
be turning off optimization for compiling C files, and you will
have set the proper -I flag for the C++ compiler too, not just the C
compiler.
