Sure that's very easy (the attached should do the job), is this
something you'd like to have a local modification or a change in the
branch?
If the case is the second before I'd just like to understand why the
Windows toolchain needs debug symbols for function names and if this is
a bug or the expected behavior.
IME this was never the case on systems I've worked on and this is why I
though having debug symbols and dump pseudo C code together in the same
debug level made sense, essentially to allow stepping.
Thanks
Andrea
