For the hell of it, I whipped my copy out, since I was in the mood.

Indeed, if one looks at page 47 of Technical Corrigendum 2 of the C99
document, one learns that:

   An array type describes a contiguously allocated nonempty set of
   objects with a particular member object type, called the element
   type.

Note the phrase "contiguously allocated", which is a term of art in
the document meaning precisely what you think it means.

There is other text that similarly requires that array members be
allocated consecutively. I'll dig it out as many examples as people
insist on.

The original claim simply has no basis in fact.
