    Btw, the impact of the bug is probably zero: I bet that on a typical Linux
    system, not a single program is compiled with -ftrapv. (Try googling for
    "+cflags +frapv". All occurrences that you find are commented out.)

You're probably right--but if we're having a discussion about the
GNU/Linux system, please let's not call it "Linux".

(See http://www.gnu.org/gnu/gnu-linux-faq.html for more explanation.)
