+Subject: [PATCH] Fix compliation error with GMP long long limbs.
+
+Depending how GMP is configured the macro from flint, slong, which actually
+refers to GMP's mp_limb_signed_t, may be a long long instead of plain long.
+
+numeric doesn't have a constructor for long long, leading to an ambiguous
+overload error on the constructor.  In this case it should make more sense
+to just use normal int and long types for these loop variables as it
+makes sense to, and only cast to the "slong" type when passing to the
+flint interface.
