It's as simple as:

svn diff \
http://svn.refractions.net/postgis/tags/1.1.4/lwgeom/lwgeom_geos_c.c \

That just gives that one single change in ptarray_from_GEOSCoordSeq

Now pipe that through | patch -R in the lwgeom directory, and it's
reverted. :-)

That fixes the regression tests on AMD64, at least against GEOS 2.2.1 (I
don't have 2.2.3 around yet.)

But I now noticed that I've failures on test 14 and 28 on my 32-bit
developer machine, with and without the patch. I'll dig into this further...
