  According to the GMP docs, mpq_cmp():
  "Compare op1 and op2. Return a positive value if op1 > op2, zero if op1 =
  op2, and a
  negative value if op1 < op2.
  "
  Does anyone know about what this return value actually is? On my machine
  (pentium M),
  * op1 > op2 always returns 1
  * op1 == op2 always returns 0
  * op1 < op2 always returns -1
  Is this conventional or architecture-dependent?
  
I cannot tell you the actual values, since they are secret.

But one thing is sure, the value will vary with GMP release.
When I test the sevelopmnt code, I get +4711 for 0, and -17,
respectively.
