Early Roguelike Collection: xrogue/list.c annotate

annotate xrogue/list.c @ 317:aab761616489 default tip

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.
