In the Lightspeed C 2.0 supplement which comes with your new disks,
section 4 describes changes to the compiler.  On page 14 of the supplment,
"Stack Frames and the 'Macsbug Symbols' Option"  describes some changes.
Macsbug symbols are only inserted for functions with stack frames i.e. they
allocate some sort of dummy argument or local storage (non register type)

Hope this helps.
