... just to keep you updated, I'm finishing testing the below, appears to work
well. Still missing: comments about ABI (no throw()) vs our specific libsupc++
implementation (suggestions very welcome ;)

Totally ;) And, for what is worth, I totally agree with your analysis.
Essentially, as far as I can see, only a TREE_NOTHROW (fn): line in
except.c:do_begin_catch is missing to complete the "baseline project" ;) Patch
forthcoming (I hope)
Thanks!
Paolo.

Yes, I realized in the meanwhile, via my usual layman investigations using nm.

Ok. Actually I can clearly remember when you advertised the use of throw()

Hi all, hi Joseph,
