* If the 'file specific' debug class level >= level OR the system-wide
* DEBUGLEVEL (synomym for DEBUGLEVEL_CLASS[ DBGC_ALL ]) >= level then
* generate a header using the default macros for file, line, and
* function name. Each call to DEBUG() generates a new header *unless* the

* See debug.c:dbghdr() for more info.
*
* Example: DEBUG( 2, ("Some text and a value %d.\n", value) );

* DEBUGC()
* If the 'macro specified' debug class level >= level OR the system-wide

* Example: DEBUGC( DBGC_TDB, 2, ("Some text and a value %d.\n", value) );
*
* DEBUGADD(), DEBUGADDC()
* Same as DEBUG() and DEBUGC() except the text is appended to the previous
* DEBUG(), DEBUGC(), DEBUGADD(), DEBUGADDC() with out another interviening
* header.
*
* Example: DEBUGADD( 2, ("Some text and a value %d.\n", value) );
* DEBUGADDC( DBGC_TDB, 2, ("Some text and a value %d.\n", value) );
*
* Note: If the debug class has not be redeined (see above) then the optimizer
