# 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
#     . ${srcdir}/${with_multisrctop}../../config-ml.in
#   else
#     . ${srcdir}/${with_multisrctop}../config-ml.in
#   fi
# else

#
# See librx/configure.in in the libg++ distribution for an example of how
# to handle autoconf'd libraries.
#
# 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
#
# ./
#   libg++
#   newlib
#   m68020/
#          libg++
#          newlib
#          m68881/
#                 libg++
#                 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=.
#
# 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)
# MULITBUILDTOP = 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.
# We except both to define `srcdir' and `target' (we *could* figure them
# out, but we'd have to do work that they're already done to figure them out).
# We expect Cygnus configure to define `arguments' and Autoconf to define
# `ac_configure_args'.
