Octave does not define _LIB_VERSION (note that the locations of the
multiple defintions are not in Octave code), so it looks like a compiler
problem not an Octave bug.  OTOH, I am using "gcc version 3.3.2
(Debian)" and don't see this problem, so I think it should be possible
to use gcc 3.3.2 to build Octave.
