This is a very old version.  You need to get the latest version
(currently 3.79.1).

There have been improvements to this version which may obviate some of
your changes.  For example, if you use the -p option to generate the
makefile database, it will show each variable, it's value, and where
(file name and line number) it was defined.

There are also various different values for debug options you can set.
