I use some code written by Fred Fish called "debug."
Statements are coded directly into the program and selectively compiled.
They look like--

DBUG_ENTER("functionName");

DBUG_PRINT("keyword", ("printf format control string", varargs));

DBUG_RETURN(functionReturnValue); /* or DBUG_VOID_RETURN; */

These are macros which invoke the debug functions.  They do nothing
if DBUG_OFF is defined.

DBUG_ENTER/DBUG_RETURN enable function entry and exit tracing.
DBUG_PRINT only gets printed if "keyword" is in the keyword list.
keywords, printing, tracing, etc. is controled with -# argument in
the argument list when you run the program.

There are other features.  If this is what you're after, say so and I'll
rustle it up.
