[postgis-devel] Warnings compiling PostGIS 1.2.1 with GEOS 3 RC4

[Mark Cave-Ayland]

Hi guys,

I get the following warnings from lwgeom_geos_c.c on Win32 when
compiling PostgreSQL 8.2/PostGIS 1.2.1 against GEOS 3.0.0rc4, but not
against GEOS 2.2.3. Does anyone know whether or not this will cause
problems?
