postgres Linux on i586 regression tests

Postgres 6.4.1 (checked) / Linux 2.0.36 (RedHat 5.2) / glibc 2.0.7-19

Hi!

int2.out and int4.out on Linux differs from expected .out's.

I imagine lots of people have found this problem and ignored it, but,
anyway, I think that adding two files int2-linux_i386.out and
int2-linux_i386.out won't hurt.

The files and the diffs, the later, only for your convenience, follow
attached.

On the other hand, for float8 test, linux outputs a substancial different
result - instead of echoing error, it represents the problem with NaN (Not
a Number).

Is this important ? I mean... is this behaviour unpredicted by postgres ?

Thanks!

(I also get diffs on geometry tests.. but I haven't analysed them yet...)
