Disable excessive FP optimization by recent versions of gcc.

Suggested solution from Tom Lane. Problem discovered, probably not
for the first time, while testing the mingw-w64 32 bit compiler.

Backpatched to all live branches.

Branch
------
REL8_2_STABLE

BTW, just to remind everybody: 8.2 is not live anymore.

(We probably ought to suggest to buildfarm owners that they shut down
that branch, too.)

I thought it was live to the end of this month. Didn't previous
discussion say that we'd go to the end of the stated month?

cheers

Well, when we decided to make a release in December, we decided that
was long enough for 8.2. I suggested that back here:
http://archives.postgresql.org/pgsql-hackers/2011-11/msg00578.php
and nobody complained, nor for the more official statement here:
http://archives.postgresql.org/pgsql-hackers/2011-11/msg01087.php
Also, all the public announcements about 8.2.23 have made it quite clear
that this was the end of the line for 8.2, eg here:
http://archives.postgresql.org/pgsql-announce/2011-12/msg00000.php

You can keep patching it if you want, but I've stopped.

regards, tom lane

Well, I was going by
<http://archives.postgresql.org/pgsql-hackers/2011-09/msg00952.php&gt;,
which was less than 3 months ago.

But I'll stop now. :-)
