## Revision 1.31  2002/05/02 20:12:45  geraint
## Added -Wl,--rpath to MTT_CXXLIBS. Sets the runtime linker path so that the
## sys-admin does not have to ldconfig the octave directory for -cc to work.

## Improved clarity of code generated for -cc and -oct (except ode2odes).
## Octave DEFUN_DLDs now call (rather than replace) their .cc equivalents.
##
## Revision 1.45  2002/05/02 09:30:22  gawthrop
## _ssim.m now returns t as 4th arg
##
## Revision 1.44  2002/05/01 17:30:56  geraint
## Improved pre-processor directives to better accommodate future alternatives (matlab)
