Hi Mark. For sure all the *library proper* headers should have (and afaik, have
already) the pragma. If I understand correctly, the doubt is about the
libsupc++ headers: at some point in the past we discussed that briefly and we
came to the conclusion that if we could avoid decorating those too it would be
cleaner (Gaby agreed, I'm 100% sure). But indeed, nothing set in stone, at
least for 4.5.x, if we want to decorate the few user visibile headers in
libsupc++, I do not object.
