/*   Debugging On or Off ?
 *   We have three kinds of debugging:
 *      a) Behaviour tracing: a lot of messages nearly on every
 *         function entry are produced if DEBUG is switched on.
 *      b) Assertion checking: only if an assertion fails, an
 *         appropriate message is produced.
 *      c) Node tracing: This is basically the same as the behaviour
 *       tracing. At each function entry, the status of a node
 *       will be printed. This happens if CHECKNODE is defined.
 *       See step0 for the selection of the node to be traced.
 *   Behaviour or node tracing is only needed in very serious cases.
 *   The macros "debuggingmessage" can be redefined to do some special
 *   tests on every entry.
 *   Assertion checking can always be done, because it is silent
 *   as long as no error occurs. But it consumes runtime.
 *   This all can also be defined in the head of a module before
 *   #include "globals.h", to debug only this module.
