I'd say no, simply because it does not meet my definition.  A definition
like this is given for a purpose, and without one it's hard to say how
good or how bad a definition it is.  But if the purpose were to allow a
future C standard to say "tail calls will be optimised" there would be
some merit in making the definition syntactically simple.

You could make it more fiddly by using C's sequence points (or the new
terminology about sequencing) to include cases like yours and also

  return ..., g();
  return f() || g();
  return f() && g();

but I don't think I would.  After all you don't want the definition of one
optimisation to preclude the possibility of others that may depend on
code re-ordering.
