Well, in theory you are right.  In practice, the restrict macro tries to
get a spelling that is likely to be accepted by the C++ compiler as
well, and the inline case checks for a specific compiler bug:

# HP C version B.11.11.04 doesn't allow a typedef as the return value for an
# inline function, only builtin types.

I can only check B.11.11.20, and it does not seem to have that bug (any
more).

Cheers,
Ralf
