longjmp question

[Jim Dehnert]

I'll add the issue.  But...

Implementation is a significant issue.  The normal longjmp implementation
is very simple -- setjmp stores the register/stack state, and longjmp
copies it back and branches.  There is normally no traceback involved,
so what you suggest is a dramatic change, and probably would make C
people very unhappy.  Furthermore, C++ users have the option of using
C++ exceptions, which have the effect you seek.
