// Revision 1.1.1.1  1999/03/16 18:05:57  aram
// Originals from SMIME Free Library.
//
// Revision 1.5  1995/07/24 15:33:34  rj
// changed `_' to `-' in file names.
//
// any-test.[hC] becomes any.[hC] due to to snacc's new file name generation scheme.
//
// check return value of new.

// Revision 1.4  1995/02/18  13:54:03  rj
// added #define HAVE_VARIABLE_SIZED_AUTOMATIC_ARRAYS since not every C++ compiler provides them.
