thanks for doing this.  however, i noticed one problem:

(3) an ELF global symbol `__foo50' implementing its new signature (yes,
    `__foo50', not `__foo60').

this is not actually the way we'd *prefer* to do it, and it's beeon this
this way most of the time in the past, but not always.  that your main
example for time_t change got it wrong isn't any excuse to continue the
problem.  (c.f., vfork14 which might be a better example?)

if we changed in 6.0, the new symbol should say "60" in it.
