I would like to implement exception handling in C (using long jumps?)
and I was wondering if anybody has done it already.  This exception
handling should be in the style of C++/Ada.  Here is an example of how
it can work:

func() {
    ....
    PREPARE_TO_CATCH( BAD1 );
    PREPARE_TO_CATCH( BAD2 );
    ....
    doStuff1();
    doStuff2();
    ....

    CATCH( BAD1 )
     ....
    END_CATCH( BAD1 );

    CATCH( BAD2 )
     ....
    END_CATCH( BAD2 );
    ....
}

doStuff1() {
    ....
    if (bad_situation1) {
     RAISE(BAD1);
    }
    ....
}

doStuff2() {
    ....
    if (bad_situation2) {
     RAISE(BAD2);
    }
    ....
}


Please answer by e-mail as I do not read these newsgroups.
If I can make it work and there is enough interest, I will post
the solution.
