  In gmp 3 the library symbols are __gmpz_init and the like, you should
  use that instead of just mpz_init.  The next gmp release will have
  some notes on this.
  
Isn't the proper to check for GMP to #include gmp.h
in such probing code?  We might want to play with
the names used in a static (not dynamic!) libgmp.a,
making any fixed test unreliable.
