Finally, mark the numeric(const cl_N&) ctor as explicit.
This allows one to mix the code using GiNaC and CLN, i.e.
cl_N x, y;
// initialize them
cl_N z = sin(x) + y*exp(y);
symbol a("a");
ex e = exp(a);
const numeric denom() const;
int int_length() const;
// converting routines for interfacing with CLN:
- numeric(const cln::cl_N &z);
+ explicit numeric(const cln::cl_N &z);

void print_numeric(const print_context & c, const char *par_open, const char *par_close, const char *imag_sym, const char *mul_sym, unsigned level) const;
