[postgis-devel] Packaging PostGIS for Windows - which to choose?

[Paul Ramsey]

Go with (ii).  We've just tried some serious work on (iii) and run  
into some un-debuggable problems (if the problem happens to be in  
libgcj, you're SOL), so unfortunately it looks like we're going to be  
stuck with GEOS for a while longer.

There should be more maintainer effort around GEOS again over the  
next few months, but I can't promise anything in the shortshort term.
