Geeat!  And people disagreeing with you on this point are not necessary
customer unfocused.

I'm quite disappointed you reduced this issue to liking/disliking ObjC++.
If you believe that is the appropriate reduction, this is my last
message on the issue.  The rest clarifies what I said earlier.

This issue has nothing to do with liking or disliking ObjC++, not
matter how much of "hostility" or other "emotion" you would like to
inject into it.  ObjC++ got it wrong, it got it wrong.  The place to
fix it is in ObjC++.  That has nothing to do with liking or disliking
ObjC++.

I would not guess that it is partly because you seem to approach the
issue only from ObjC++-centric point of view.  This is issue is not
just fixing ObjC++ by uglifying libstdc++.  Those macro definitions of
try/catch when -fno-exceptions have been there long before ObjC++ came
in.  It is not like we're suddenly changing them.  
The uglification you're proposing is also breaking interfaces:  All
user codes that worked with both -fexceptions and -fno-exceptions and
used try/catch now will break.  I don't think I'm prepared to accept
that breakage.  The fix is simple for ObjC++: #undef them if it thinks
it wants both -fno-exceptions, libstdc++ headers.
