I'm not familiar with stow. Does stow create some kind of symlinks from /home/santi/usr/stow/git to home/santi/usr ? If so, why can't you use prefix=/home/santi/usr/stow/git both in 'make' and in 'make install' ? Would this work ?

BTW, is it possible to have git use argv[0] to automatically determine the executable_dir without compiled-in paths ?
