What is the difference? I do not see "well-defined" in the "Terms, definitions, and symbols" part of the standard.

  It is 'de facto' defined. http://en.wikipedia.org/wiki/De_facto http://en.wikipedia.org/wiki/De_facto :)

    "de facto" defined means nothing. Compilers change and break programs that depend on undefined behavior all the time.
