How are you going to handle catching exceptions, given that we have no
way to recognize certain types in C (templates, classes, etc)?  See
rth's post about catching exceptions in C.

Besides, this is just a first step.  What other compilers have done
(m$oft) is provide a try/finally/__except.  Where the __except can
catch exceptions.  But they've hand waived over the issue as well and
__except catches *any* exceptions (ala catch(...)) because they've
obviously run into the same problem of type interoperability between
languages.

try/finally is a way to run cleanups, not to implement a full fledged
EH mechanism for C.  If you want that, you should be using C++.
