Unfortunately, many linkers do not accept contentless object modules.
If you say that's a stupid way to design linkers, I would agree, but
it doesn't change the fact that such linkers exist.  Therefore the
"universal" definition for the language must require of a strictly
conforming (i.e., maximally portable) program that it contain SOMEthing.

Actually, I think this should have been: SOMEthing with EXTERNAL LINKAGE,
since about as many linkers have problems with that as with empty objects.
The proposed Standard does not seem to specify this the way I thought we
intended; it seems to permit a translation unit to have just an object
declaration with internal linkage, so long as the object is not used in
an expression.
