# Configure fragment invoked in the common section for subdirs
# wanting multilib support.
#
# The common section was chosen because xiberty clobbers $srcdir in the
# common section of its configure.in.
#
# The intent is to keep as much of this in one place as possible (and out
# of each subdirectory, eg: newlib, libio, etc.) until the right way to do
# this (ha ha) is decided upon.
#
# This is where a target selects what multilib directories to build.
# It is advisable to support a few --enable/--disable options to let the
# user select which libraries s/he really wants.
#
# Subdirectories wishing to use multilib should put the following lines
# in the initial ("common") section of configure.in:
#
#if [ -n "${with_multilib_top}" ]; then
# . ${with_multilib_top}/../cfg-ml-com.in
#else
# . ${srcdir}/../cfg-ml-com.in
#fi
#
# `with_multilib_top' exists to handle the case of configuring in the source
# tree: ${srcdir} is not constant.
#
# The following should be added to the "post-target" section of configure.in:
#
#if [ -n "${with_multilib_top}" ]; then
# . ${with_multilib_top}/../cfg-ml-pos.in
#else
# . ${srcdir}/../cfg-ml-pos.in
#fi
# FIXME: Multilib is currently disabled by default for everything other than
# newlib. It is up to each target to turn on multilib support for the other
# libraries as desired.
#
# FIXME: It would be better if we could use the --print-multi-lib switch to
# gcc to get the list of directories to build, but at this point the compiler
# has not been built.
# Only do this if --enable-multilib.
# And only if at the top level, not a multilib subdirectory.
if [ "${enable_multilib}" = yes -a -z "${with_multisubdir}" ]; then
# Doing this in the common section means ${target} isn't set yet, so compute
# a copy here. This is a bit kludgey, but again the current (short term) goal
# is to be as unobtrusive (sp?) to the rest of the sources as possible.
if result=`${config_shell} ${configsub} ${target_alias}` ; then
true
else

# Note that not all of these will be built for a particular
