Thunderbird, enigmail, and GCC 3.4

Hi, Coleman,

Finally I caught the issue for thunderbird.  It was due to the
difference between our floating point handling and Linux's counterpart.
~ The patch attached would fix the problem at thunderbird part.

Unfortunately enigmail plugin compiled with gcc 4.x as shipped with
FreeBSD 7.0+ would still crash with Signal 11, but with gcc 3.4 it would
work fine.  I have not yet figured out why this would happen...

Cheers,
