Many thanks, Pierre. At the end, it compiled with GDAL 1.7.1. Now, the
problem is a pretty

ERROR: could not load library "c:/postgres/lib/rtpostgis.dll": The
specified module could not be found

while executing rtpostgis.sql. The file rtpostgis.dll does exist in
its location (c:/postgres/lib). And I've tested with:

- Copying rtpostgis.dll to /c/postgres/bin (I had to do something
similar with libpq.dll)
- Setting LIBDIR to "/c/postgres/lib" and "c:/postgres/lib" and
restarting the server

It didn't work. Any ideas?

Thanks again, and best regards,
Jorge
