Ah, I meant the interface to be standardized on AMD64 Linux.. Don't know 
what MS is doing in that direction.

Exceptions do have advantages: You don't need to ask on every 
sub-routine call if it has failed - instead the subroutine will tell 
you. So you save (run)time by omitting these checks - at the same time 
you are still on the safe side..

I would say 'why not add them?'. :-)

Every language (not only C++) can catch other languages exceptions.. So 
I wouldn't call that C++ ABI - instead it's more of an platform ABI.
