 CHICKEN 4's setup-api provides {{{version>=?}}}, whose code is in CHICKEN
 5 but not exposed to users.  That leads to a lot of copy&paste of that
 procedure into the source of eggs.

 This code could be an egg, but then it is needed by CHICKEN anyway, and
 has been stable enough not to require any modification along the entire
 time CHICKEN 5 has been available, so unlikely to require a lot of
 maintenance in the future.

 The following eggs copy&paste the definition from CHICKEN 4:
