Why is my third coord ignored ? I can see that the 'coords' attribute

set to 3, so as I understand, the 3rd value should be used... ?
The WKT writer in GEOS does not serialize 3D coordinates by default:

If you're adventurous, you can try enabling the PRINT_Z macro. GEOS only
supports exporting 3D information as EWKB/HEXEWKB.
Thanks for your answer :)
Strange thing is that with stock Debian sid, it works as expected
without doing anything. I'll try to find what is causing this difference
in behavior (haven't seen any ref to PRINT_Z macro in debian package).
Cheers,
Marc
