Non-optimized.

Maybe, but I do not know whose will. I know how it happens, but not when.
Anyway, I mailed Eli and asked him immediately since I feared my pc
might hang (which it can do sometimes when bugs jumps in). Thee is a
bug in w32fns.c where this happened. There should be a check if f is
0.
There seems to be more places where this is not checked. I will look
through them and add a patch here.
