# Things are complicated because 6 separate cases must be handled:
# 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
# The build tree is layed out as
#
# ./
-# libg++
# newlib
# m68020/
-# libg++
# newlib
# m68881/
-# libg++
# newlib
#
# The nice feature about this arrangement is that inter-library references
# newlib. It is up to each target to turn on multilib support for the other
# libraries as desired.
-# We have to handle being invoked by both Cygnus configure and Autoconf.
-#
-# Cygnus configure incoming variables:
-# srcdir, subdir, target, arguments
-#
# Autoconf incoming variables:
-# srcdir, target, ac_configure_args
+# srcdir, host, ac_configure_args
#
-# We *could* figure srcdir and target out, but we'd have to do work that
+# We *could* figure srcdir and host out, but we'd have to do work that
# our caller has already done to figure them out and requiring these two
# seems reasonable.
+# Note that `host' in this case is GCC's `target'. Target libraries are
+# configured for a particular host.
