Speak up if you use #define _HAS_EXCEPTIONS

I am trying to understand number of customers use this #define and user
scenarios it is currently used in. If you see #define _HAS_EXCEPTIONS in
your source code, could you please reply to me directly or just comment here info on

- what kind application is this?

- what are reasons to use this #define?

- how big is an impact on you if this #define was removed from STL inVS2005?

Please specify in your reply if you want me to post your comment online. Yes is assumed by default.

Thanks,
Nikola
