From 2f9bcf9713523f6fefecd143cc2aa2a8dda7f27f Mon Sep 17 00:00:00 2001

Subject: First step of "autoconfization". Created a configure script which
 guesses most system-dependent parameters and determines name of system
 configuration file (sysdep/cf/...) with the remaining ones.

To compile BIRD, you now need to do:

	autoconf		# Create configure from configure.in
	./configure		# Run configure script
	make			# Compile everything

Configuration files:

	sysdep/config.h		Master config file
	sysdep/autoconf.h	Parameters determined by configure script
	sysdep/cf/*.h		Fixed system configuration we're unable
				to guess.

Makefiles are still the original ones, but this will change soon.
