Ok I fix this.
I have not found the rule for maximum column in Config.in and *.mk files 
in the manual. Maybe we should add.

Ok, I didn't know that it was the default value. I fix this.

Ok I fix, good idea.

The --disable-lensdata disable an included Nikon lens database for 
conversion to readable lens name and this database is free use only in 
non-commercial projects.

For the --disable-nls, I don't know exactly why it's requested in 
commercial version.
This is what is specified in the README file.

It works in both cases because XMP is automatically enabled if expat is 
found.
