I had a look. It worked for me in a simple scan:

$ ./nmap -sC -sV scanme.nmap.org

Some files in the branch have been marked as executable. I found them
this way:
git diff master... | grep -B 2 'new mode'

It's worth mentioning that there's a new "bits" library that contains a
"reverse" function. As I gather, it's to replace some former uses of
bin.pack and bin.unpack, where a string would be packed with "B", then
reversed as a string, then unpacked with "B" again.
