+# Configure fragment invoked in the post-target section for subdirs
+# wanting multilib support.
+#
+# It is advisable to support a few --enable/--disable options to let the
+# user select which libraries s/he really wants.
+#
+# Subdirectories wishing to use multilib should put the following lines
+# in the "post-target" section of configure.in.
+#
+# if [ "${srcdir}" = "." ] ; then
+# if [ "${with_target_subdir}" != "." ] ; then
+# . ${with_multisrctop}../../config-ml.in
+# else
+# . ${with_multisrctop}../config-ml.in
+# fi
+# else
+# . ${srcdir}/../config-ml.in
+# fi
+#
+#
+# Things are complicated because 6 separate cases must be handled:
+# 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
+#
+# srcdir=. is special. It must handle make programs that don't handle VPATH.
+# To implement this, a symlink tree is built for each library and for each
+# multilib subdir.
+#
+# The build tree is layed out as
+#
+# ./
+# newlib
+# m68020/
+# newlib
+# m68881/
+# newlib
+#
+# The nice feature about this arrangement is that inter-library references
+# in the build tree work without having to care where you are. Note that
+# inter-library references also work in the source tree because symlink trees
+# are built when srcdir=.
+#
+# Unfortunately, trying to access the libraries in the build tree requires
+# the user to manually choose which library to use as GCC won't be able to
+# find the right one. This is viewed as the lesser of two evils.
+#
+# Configure variables:
+# ${with_target_subdir} = "." for native, or ${target_alias} for cross.
+# Set by top level Makefile.
+# ${with_multisrctop} = how many levels of multilibs there are in the source
+# tree. It exists to handle the case of configuring in the source tree:
+# ${srcdir} is not constant.
+# ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881).
+#
+# Makefile variables:
+# MULTISRCTOP = number of multilib levels in source tree (+1 if cross)
+# (FIXME: note that this is different than ${with_multisrctop}. Check out.).
+# MULTIBUILDTOP = number of multilib levels in build tree
+# MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...)
+# (only defined in each library's main Makefile).
+# MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000)
+# (only defined in each multilib subdir).
+
+# FIXME: Multilib is currently disabled by default for everything other than
+# 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, host, arguments
+#
+# Autoconf incoming variables:
+# srcdir, host, ac_configure_args
+#
+# 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
