Thanks! posix-shell.m4 comes from gnulib so it would be nice if you could send the patch there and discuss the issue with gnulib developers. Perhaps there is a reason why the shells are tested in that order, although the gnulib commit messages don't have any reasoning. A guess is that someone might prefer if the same shell is used for running configure and the test suite scripts. Anyway, getting it fixed in gnulib would get it fixed in projects other than XZ Utils too. One can force the POSIX shell to a specific value on the configure command line by passing, for example, "gl_cv_posix_shell=/bin/sh" as an argument. It's not documented in the --help output but it's mentioned in INSTALL section 3.1. That is an alternative to patching to get reproducible builds. -- Lasse Collin | IRC: Larhzu @ IRCnet & Freenode
