Just because there's a standardized interface doesn't mean it has to be
used. :-)  I wonder if Windows Structured Exception Handling uses it...

That would be an argument for extending the C language.  Would anyone
else like MSVC-style __try/__catch/__finally blocks?  Or am I just a
sick bastard?

This only requires that the compilers agree in the C++ ABI.
