Hi Dominique,
I would expect you to need -gstrict-dwarf in CFLAGS_FOR_TARGET also
but the point of my question is to find a way of having this on by
default on Darwin (which is what we currently seem to need).
(more research is need on the latter - to determine whether the
problem lies in our emission of debug fragments - or in the tools
cheers,
Iain

I am currently at stage 3 and I see -gstrict-dwarf in the log file.
I don't know if it is the Right place, but it seems to work so far.
Cheers,
Dominique
