// Purpose:     Trace and assert functions

// Description: The functions in this file are null implementations of the

//              standard trace and assert functions. These can be used to

//              eliminate all trace and assert messages without recompiling.

//  asserts enabled - of course if it does, assert() maps to the chosen

//  implementation; if not, it's the same inner function to breakpoint.)
