[aspectc-user] Catch exceptions in main()?

Hi Markus!

You might be pleased to hear that Puma, AspectC++, and Ag++ are no 
longer compiled with "-fno-exceptions -fno-rtti". AspectC++ and Ag++ now 
have exception handlers in main() (as you proposed). We evaluated the 
overhead and found that it is no problem for the Puma library.

Best regard and thanks for your hint,

Olaf
