// Revision 1.1.1.1 2000/08/21 20:36:07 leonberp
// First CVS Version of SNACC.

// Revision 1.5 1995/07/24 15:36:03 rj
// check return value of new.
//
// changed `_' to `-' in file names.
//
// Revision 1.4 1995/02/18 13:54:18 rj
// added #define HAVE_VARIABLE_SIZED_AUTOMATIC_ARRAYS since not every C++ compiler provides them.
