But I insist; for me, as a source code auditor, tools like yours do
not help.

They are crutches.  I bet that most people will use your tool, and
then get a nice happy feeling thinking they are safe.

A complete source code read is needed.

I have deleted your comments on changing stdarg, since any changes
like that are not ever going to happen.
