Yes - I now forced -Wall on xgps in any case, and for both C and ObjC.

Just an idea - should we perhaps keep the -O2 flag even when debug=yes is
used ?

That would make sure when you use debug=yes you get all the warnings ...
<and I think if you use debug=yes, it's because you are debugging and
definitely you want as many useful warnings as possible - in particular,
you *do* want the flow analysis warnings>

 I'm quite sure gcc is supposed to be able to manage `-O2 -g' pretty well
... but perhaps it might make things more difficult when debugging ?

Does -O2 cause problems when debugging ?
