//
// We define three levels of debug support:
//
// Highest DBG=1, TRC=1 Invasive debug
// Middle DBG=0, TRC=1 Safe debug
// Lowest DBG=0, TRC=0 No debug
//
// Safe debugging
//
// o Assertions and other failure trace messages
// o Flag controlled trace messages
//
// Invasive debugging adds
//
// o Unflagged trace messages
// o Extra cross checking fields in internal structures
// o Extra win32 api calls for validity checking
// o Performance measurements
//
// As long as no error situations occur, safe debugging should produce
// no messages on the debugging terminal.
//
// 'Checked' builds are always compiled with DBG=1, TRC=1.
//
// 'Free' builds are compiled with safe debugging until
// shortly before release, then for the last releases with no debugging.
//
// Care should be taken to ensure that the presence of safe debugging
// code does not change operation in any way, as there is little time
// at the end of the project to validate this.
