I'm working on packaging minidlna for debian , which implied a few changes that you might be interested in applying upstream. It's mostly small changes that you may find unnecessary, so feel free to reject those patches, but I thought it was worth at least letting you know about it. You can also find all this changes in my git repository .
So here it goes. This first patch is just to bring the Makefile to the GNU standard , using DESTDIR instead of PREFIX to specify the target installation directory tree.
