The wget method has the advantage that you don't have to remember 'make 
release', it is regenerated automatically when you create the tarball (make 
dist, make distcheck).
Another advantage is that wget doesn't need get2cl - which might not be 
available on e.g. Solaris.
E.g. 'gengetopt' is not available there and it was not possible for me to 
built it (some auto* stuff was not compatible). That means I can't build 
libidn2 there at the moment. IMO, such dependencies are a waste of time since 
they just solve trivial tasks, basically nothing.

Maybe it is possible to use gnulib's git-to-changelog instead of git2cl ?
