gcc-2.95 is a lot more strict than previous versions and that causes a few
minor problems. The problem here is that finite() prototype is not visible
to the compiler, and that is illegal C++.

Workaround for now: Use -fpermissive for now (add that to XTRA_CXXFLAGS
in <build_root>/Makeconf).

Solution: Apply the following patch:
  
  $ cd <octave-2.0.14>/liboctave
  $ patch -p0 -s < /tmp/lo-mappers.cc.diff

        * lo-mappers.cc (ieeefp.h): Include conditionally.

Note that you'll also need a fix from JWE for src/sysdep.cc (search for
`tputs' in bug-octave mailing list for that patch).
