That's what I thought, too, but when Ron said (in email) that gcc didn't like
them all, I checked the ANS.  3.7.2 says "if the declaration... is a tentative
definition and has internal linkage, the declared type shall not be an
incomplete type".  This seems to make array7 and array10 illegal.

It's also a pretty stupid rule, in my opinion.
