--- Comment #30 from Jonathan Wakely <redi at gcc dot gnu.org> --- Solaris /bin/echo doesn't understand -n jwakely@gcc-solaris11:~/src/gcc$ ./contrib/gcc-git-customization.sh -n Your name [Jonathan Wakely]? -n Your email address (for git commits) [jwak...@redhat.com]? -n Local name for upstream repository [origin]? Richard's patch fixes it for Solaris: Your name [Jonathan Wakely]? Your email address (for git commits) [jwak...@redhat.com]? Local name for upstream repository [origin]? I'd have done printf "%s [%s]?" "$question" "$default" instead, but they're equivalent. Given that I've tested it and you're a global maintainer, I said push it!
