It's a bit late for that change.  You could warn at configure time if
a "broken but acceptable" version is detected, like we do for
gmp or mpfr (I don't remember which one).

Re: g++; operator==

[Richard Guenther]

First of all, this mailinglist only tracks bugzilla
(http://gcc.gnu.org/bugzilla) activity, so getting help
this way is going to fail.

Second, your testcase is invalid C++, to fix it, change
operator== to

   bool operator== (const Int& i2) const {
   return (this->i == i2.i ? true : false);
   }

as you cannot bind a temporary (which Int(2) is) to an
lvalue reference.

Your other compilers are wrong in accepting the code.

Richard.
