--- Comment #16 from Rick Regan <exploringbinary at gmail dot com> ---
I can no longer find any conversions that gcc (I'm using 4.6.3) performs
incorrectly, including the examples cited above. It doesn't look like there has
been any related code changes in real.c though. Is this an
architecture-dependent bug perhaps? When I first tested this three years ago I
was on a 32-bit Intel machine; now I'm on a 64-bit machine. Thanks.
