Daniele,

I see the nmake.opt in subversion lacks the MRSID_FLAGS = -DMRSID_J2K
required to enable the JP2MRSID driver.  I have added this in trunk and
1.4 branch.  But basically just add this in your nmake.opt, just after
MRSID_LIB for instance:

# Comment out the following to supress JP2MRSID driver.
MRSID_FLAGS =	-DMRSID_J2K

Best regards,
