Some more information on this issue.
If we use GDAL to access a TIFF file, SHAPEPATH is used.
If we use GDAL to access an ECW file, SHAPEPATH is not used!
How is this possible?

Hi list,
using Mapserver 4.8.3 and GDAL 1.3.2 we have a problem accessing an ECW
file relative to the SHAPEPATH. If we use an absolute path in the DATA
statement all works fine.
So:
MAP
SHAPEPATH "/data/geopakhuis/"
and:
LAYER
DATA "aerogrid_nl2005/Aerogrid_NL2005_40cm.ecw"
does not work (case 1), whereas
DATA "/data/geopakhuis/erogrid_nl2005/Aerogrid_NL2005_40cm.ecw"
does work (case 2).
Attached the log after setting CPL_DEBUG to ON.
Case 1:

Any ideas what could be wrong?
