comparison build-aux/config.guess @ 317:aab761616489 default tip

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Rearrange some Autoconf files. Autoconf was failing to detect install-sh at the top level and needed some explicit directions. It also wants config.guess and config.sub to be provided too. A few other macros have also been updated.
