/*
* last parameter in the trace_even and trace_interval_entry call is
* the stack level to report the PC in the trace record. so 0 means
* the PC of the current frame, 1 means the PC of the caller, etc.
* there's a dilemma here - these macros are included in the inline
* _mutex calls which get called from the (created during build)
* mutex functions in the mutex .c files. in that case, the level
* should be 1 - we don't want the PC of where in the mutex function
* the trace call is happening, we want the PC of whomever is calling
* the mutex function.
*
* but.. an app can call the inline functions - it can #include the
* appropriate libsync mutex .h files, and call the inlined _mutex
* function in their code. in that case, the appropriate level for the
* trace calls would be 0 - the user would want to know where in their
* code the call to the _mutex function is.
*
* so, we'll assume _LEVEL of 0 which is what the inline funtions need.
* when we build the files for libsync, we'll do a -D_LEVEL=1
