I tried something, using patch git repo's master instead of release tarballs, I am not sure the git repo contains all the fixes, we could alternatively just pull patches from Debian.
This attempt does not work yet however, it fails on some gnulib source file not being found for some reason: gcc: error: parse-datetime.c: No such file or directory gcc: fatal error: no input files compilation terminated. This file seems to be generated by YACC from earlier log.
