## Revision 1.293.2.2  2001/02/23 03:53:53  geraint
## Minor revisions. (ode2odes.exe works on GNU/Linux and ~GNU/Irix)
##
## Revision 1.293.2.1  2001/02/22 06:41:40  geraint
## Initial merge of ode2odes.exe into main mtt.
## standalone_rep.make deleted: rules moved to mtt, variables to mttrc.
##
## Revision 1.293  2001/02/06 04:39:08  geraint
## Added _standalone.exe representation.
##
## Revision 1.292  2001/02/05 17:27:40  gawthrop
## Make sure _def.r exists before creating _state.txt
##
## Revision 1.291  2000/12/27 14:50:40  peterg
## This is the first CVS version (4.9).
## Commented out code now deleted
