//   Note: 
//      For builds without DEBUG defined (FRE builds), calling
//      code will reference an underscore version of all public 
//      logging routines (_xxx()).  These functions are defined
//      as inline with little or no code (no code means no caller 
//      code is generated).
//
//      For DEBUG defined (CHK) builds, the calling code connects
//      with the normally named logging routines.
//
//      This is done to keep calling code to a minimum for FRE
//      builds, to avoid LOG2(), LOG3() type defines that vary
//      with param count, and to keep build system happy when
//      mixing FRE and CHK callers and libraries.
