H98 indeed says nothing about separate compilation, and it is indeed
an issue for the implementation.

What H98 does is it defines a language for which separate compilation
is at best extremely difficult and at worst virtually impossible
without extra information which is not part of H98 (such as GHC's
hi-boot files).

Exactly.
