As far as I know, set_new_handler is still a standard part of the
language, I think.  In my copies of g++ (egcs 1.1a and gcc 2.7.2.x) it
is defined in libgcc.a.  However, I notice that in egcs, the name in
the library is mangled, but in the gcc 2.7.2 library it is not.  I
assume that the compiler should be handling this detail though,
because I've not had trouble compiling Octave with egcs on Linux
systems.
