[postgis-users] different results for area with different programms

[Martin Davis]

The JTS area algorithm has been tweaked slightly recently, but that's 
not it - I get the same answer with JTS 1.8 (which uses the original 
algorithm).

I'm guessing PostGIS doesn't use GEOS for area, right?

Anyway, looks like it's fixed in the latest version.
