Hi all,

For those of you that haven't been following the thread on -hackers: 
http://archives.postgresql.org/pgsql-hackers/2011-12/msg00627.php.

Basically in order to remove floating point precision errors on x86 
platforms, we need to compile with -fexcess-precision=standard. This 
would probably be a good idea for GEOS too.


ATB,

Mark.
