I'll work on this (and of course help is welcome).

Why not just post the diffs as formal patch submissions?  You
have a copyright assignment now - you could do your development
right in our CVS repository.

Yes.  This is because that type of wrapper function is invoked in
instrumented code via the renaming macros in <mf-runtime.h>, which
are not active in libmudflap itself.  It is only symbol-interposition
type wrappers that require ...REAL vs ...WRAPPED calls.
