To enable compilation of trace facilities, you must define the macro
`YYDEBUG' when you compile the parser. You could use `-DYYDEBUG=1' as
a compiler option or you could put `#define YYDEBUG 1' in the C
declarations section of the grammar file (*note The C Declarations
Section: C Declarations.). Alternatively, use the `-t' option when you
run Bison (*note Invoking Bison: Invocation.). We always define
`YYDEBUG' so that debugging is always possible.

We always define `YYDEBUG' so that debugging is always possible.
The trace facility uses `stderr', so you must add
`#include <stdio.h>' to the C declarations section unless it is already
there.
`#include <stdio.h>' to the prologue unless it is already there.
Once you have compiled the program with trace facilities, the way to
request a trace is to store a nonzero value in the variable `yydebug'.
