I don't think we've tried it anywhere, but I imagine it is pretty
safe. There's another trick along similar lines: you can try to make
a static array where the dimension is possibly a negative number.

Nice.
Your patch has a problem if sizeof(int)==sizeof(char).
Still, I prefer your approach to the current approach.
This patch is ok with me.
