/* 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.
