Have you looked at what that would take? E.g. how do you plan to deal with the sha256 code used by make-fingerprint.c and normally provided by gnulib? How 'bout doing "a bit of both": i.e. use a separate gnulib+autoconf for those two executables, but patch them when it's easy to try and minimize the reliance on gnulib and autoconf? Stefan
