Well, in fact this _is_ illegal code as it does not conform to ISO
C++.  And ISO C++ is right here, as otherwise behaviour would be
undefined when the first and the second declaration are different.
Note, that in general the compiler cannot decide equality when
reaching the second declaration.

It was decided in February this year that gcc should issue an error,
not just a warning.  You may want to read the discussion at
http://gcc.gnu.org/ml/gcc-patches/2002-02/msg01131.html.

And my personal optinion is that, if there was code that makes the
compiler more complicated just to hide a bug in the compiled
application, this code should be removed.
