Thanks, I've updated the patch to make that change automatically.

Added a note to the docs that with Wine installed, this should just work.

With Wine installed, this should work. Please update and follow the 
updated instructions for locating mingwm10.dll and modifying your 
parcels.txt file to match, before running Configure. Having done that, Box 
Backup builds fine with the cross-compiler for me on Ubuntu Hardy.

Cheers, Chris.
