Talk:Undefined behavior/to do

The article requires quite extensive reworking to be of acceptable encyclopedic level. Some thing I've noticed at a quick glance:


 * the fourth paragraph (about pragma) is out of place, either because the behavior of #pragma is not undefined, and because of the mention of pragma once as if it were the only form of pragma (incidentally, C99's STDC pragmas have a standard-defined meaning); perhaps we can replace it altogether with a warning that undefined behavior has not the same meaning as implementation-defined behavior.
