annotate rogue5/chase.c @ 164:49af2fd0bb0c

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Move some autotools files to where configure can find them. rogue5 uses config.guess and config.sub to find the canonical system names. The configure script expects them to be in the same directory as install-sh. So they have been relocated to the top level. This is a quick and dirty fix. The eventual plan is to relocate them to /dev/null. I also suspect they should be used to set HOST, not TARGET. Rogue is not a cross-compiler.
