A few comments:
Many portable C programs assume that signed integer overflow wraps around
reliably using two's complement arithmetic.
I'd replace "portable C programs" with "widely-used C programs". The normal
use of "portable" means that it conforms to the standard.

Let me make the point that signed overflow has been undefined since
before the C standard was finialized and in fact there is a nice

back in 1988.

Hello,
I'm implementing a tiny vfork/exit implementation using setjmp and
longjmp. Since the function calling setjmp can't return (if you still
want to longjmp to its jmp_buf) I implemented vfork using a statement
expression macro. Here's my implementation of vfork.
