Do I need to worry about these warnings

[Obe, Regina DND\MIS]

Finally decided to give the new 1.3.4SVN a test drive.  It compiles.
Haven't tried using it yet though, but I get the below warnings during
compile.  Do I need to worry about these?

lwgeom_geos_c.c
lwgeom_geos_c.c: In function 'GEOS2LWGEOM':
lwgeom_geos_c.c:2942: warning: assignment discards qualifiers from
pointer target type
lwgeom_geos_c.c:2951: warning: assignment discards qualifiers from
pointer target type
lwgeom_geos_c.c:2961: warning: assignment discards qualifiers from

lwgeom_geos_c.c:2966: warning: assignment discards qualifiers from

lwgeom_geos_c.c:2967: warning: assignment discards qualifiers from

lwgeom_geos_c.c:2988: warning: assignment discards qualifiers from

lwgeom_geos_c.c: In function 'polygonize_garray':
lwgeom_geos_c.c:3352: warning: passing argument 1 of 'GEOSPolygonize'
from incompatible pointer type
lwgeom_geos_c.c: In function 'LWGEOM_buildarea':
lwgeom_geos_c.c:3502: warning: passing argument 1 of 'GEOSPolygonize'
from incompatible pointer type
lwgeom_geos_c.c:3545: warning: assignment discards qualifiers from
pointer target type

I'm running the below on openSUSE 10.3
"POSTGIS="1.3.4SVN" GEOS="3.0.0-CAPI-1.4.1" PROJ="Rel. 4.6.0, 21 Dec
2007" USE_STATS"

I can't remember if I got this error before.  I don't think I was paying
too much attention if it compiled.

Thanks,
Regina

Yeah, these errors have always been there. I'm fairly sure it's to do
with changing the GEOS API to work correctly on 64-bit architectures,
however to change them to the correct types would break using GEOS <
3.0. Maybe we should consider having GEOS 3.0.0 the minimum version for
1.4 which means we should be able to eliminate them - or is that too
gutsy a call?


ATB,

Mark.
