Re: [9fans] Good enough approximation for ape/pcc

i'm not convinced this is useful.  if your program is sufficiently
complicated to warrent this sort of debugging aid, just printing
the caller's name (or pc) is most likely insufficient.  most likely
you're going to need to know the whole call stack. and likely function
arguments and locals.

i did write a pretty large billing system that announced that
selected functions had been called in the debugging log.  even if we
had been programming to c99 at the time, __func__ would not have been
useful because we also printed out the most helpful arguments to
the functions we were tracing.
