Exceptions / setjmp/longjmp question

[wysota]

Question A: Is it possible (and if yes, how) to use exceptions in a Qt4 app AND do not have the mingwm10.dll dependency (My app is compiled as statically as possible)

Yes.

Question B: Do setjmp and longjmp mess Qt up? (I've come up with a way to destruct objects when I longjmp out of a function, so this is not a problem)

Why would they? Qt is just another set of C++ libraries, nothing more, nothing less. Everything that applies to C++ applies to Qt as well.
