I know the conversation is partly about what developers should depend on or not, but keep in mind that "undefined behavior" and "implementation-defined behavior" mean something precise and completely different from each other in C99. See Chapter 3 (and 4) and informative Appendix J http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1336.pdf
