Eric,

Will the madness never end?  I sometimes wonder how much
time and system resources GDAL spends probing around looking
for a variety of possible auxilary files: many combinations
of world file, including uppercase/lowercase tests on unix,
.ovr overview files, .aux auxilary files, .aux.xml auxilary files,
.prj files, etc.

I would prefer not to apply this patch for the time being as I
feel it encourages the proliferation of worldfile extensions and
adds to the risk of an improper world file being picked up.

Best regards,
