After mentioning the difference between gcc and icc I've got this
response:
---snip---
Regarding the zero size array issue:

Objects with zero size are incomplete objects and cannot be used in any
meaningful way.  Zero length arrays are explicitly prohibited by the
Standard.  We allowed zero length arrays as a feature request.  We set
their size to one so operations involving them can make some kind of
sense.

Can you please give me "something" a compiler developer should
understand (an URL, a reference into some standard, a description, ...)?
As long as we can provide strong evidence that gcc doesn't do the wrong
thing Intel will change icc to be compatible with gcc.

Bye,
Alexander.
