* MODULE: debug.h
*
* Header file for (debug.c).
*
* Double braces are needed for output macros.
*
*     DBGMSG(DBG_LEV_ERROR, ("Error code %d", Error));
*
* This is because we can't use variable parameter lists in macros.
* The statement gets pre-processed to a semi-colon in non-debug mode.
*
* Set the global variable GLOBAL_DEBUG_FLAGS via the debugger.
* Setting the flag in the low word causes that level to be printed;
* setting the high word causes a break into the debugger.
* E.g. setting it to 0x00040006 will print out all warning and error
* messages, and break on errors.
