In the beginning the load-history features didn't exist, so that
didn't cause any trouble.  In Emacs 21 this use of eval-when-compile
was documented after discussion about defvar affecting load-history,
with a policy decision from either you or gerd.  The policy may have
changed, but that's irrelevant for people working with the available
Emacs.
