Hi All,
Sorry I just realized I never actually sent the updated patch...
So here it is :)

Hi,
this patch adds a debug function dotfn and a convenience macro DOTFN
similar to dot-fn in gdbhooks.py.
It can be used to have the compiler:
- dump a control flow graph, or
- pop up a control flow graph window
at specific moments in the compilation flow, for debugging purposes.

The attached patch enhances the -Wrestrict warning to detect more
than just trivial instances of overlapping copying by sprintf and
related functions.
The meat of the patch is relatively simple but because it introduces
dependencies between existing classes in the sprintf pass I had to
move the c

This is initial patch for
