and Autoconf macros that come with Automake. It supports multiple separate builds of the same source tree, and updates dependencies automatically. Targets info, html, install, install-html, uninstall and dist are not yet implemented. System configuration is now automatic. Previously, you had to choose one of several canned system configurations, defined in Make.sysdefs. Currently, system configuration always uses UCONTEXT for LWP, and chooses LWP only if its requirements are met. Feature configuration changed: instead of editing build.conf (further processed by doconfig), you pass arguments to configure. Note that build.conf settings that can be overridden in econfig have no configure equivalent; just edit econfig instead. Because generated headers complicate makefiles, fold gamesdef.h into its users: path.c and ipglob.c become path.c.in and ipglob.c.in, constants.c, vers.c, options.h simply hardcode defaults (most of them are run-time configurable). Call the client empire instead of emp_client. This matches what the old standalone build did.
