unconditionally disable the octave_allocator class
* configure.ac: Delete the --enable-octave-allocator option.
* oct-alloc.h: Delete octave_allocator class. Warn if file is
included. Unconditionally define macros to be empty.
* NEWS: Make note of these changes.
* oct-alloc.cc: Delete.
* liboctave/util/module.mk (UTIL_SRC): Remove it from the list.

September 2002 - Changes by Rafael Laboissiere <rafael@laboissiere.net> * Added Qbb option to normalize the input and avoid crashes in Octave. * delaunayn accepts now a second (optional) argument that must be a string containing extra options to the qhull command. * Fixed doc string. The dimension of the result matrix is [m, dim+1], and not [n, dim-1]. 6.
