L		 30# It is advisable to support a few --enable/--disable options to let the
31# user select which libraries s/he really wants.
32#
33# Subdirectories wishing to use multilib should put the following lines
34# in the "post-target" section of configure.in.
35#
36# if [ "${srcdir}" = "." ] ; then
37# if [ "${with_target_subdir}" != "." ] ; then
38# . ${with_multisrctop}../../config-ml.in
39# else
40# . ${with_multisrctop}../config-ml.in
41# fi
42# else
43# . ${srcdir}/../config-ml.in
44# fi
45#
46#
47# Things are complicated because 6 separate cases must be handled:
48# 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
49#
50# srcdir=. is special. It must handle make programs that don't handle VPATH.
51# To implement this, a symlink tree is built for each library and for each
52# multilib subdir.
53#
54# The build tree is layed out as
55#
56# ./
57# newlib
58# m68020/
59# newlib
60# m68881/
61# newlib
62#
63# The nice feature about this arrangement is that inter-library references
64# in the build tree work without having to care where you are. Note that
65# inter-library references also work in the source tree because symlink trees
66# are built when srcdir=.
67#
68# Unfortunately, trying to access the libraries in the build tree requires
69# the user to manually choose which library to use as GCC won't be able to
70# find the right one. This is viewed as the lesser of two evils.
71#
72# Configure variables:
73# ${with_target_subdir} = "." for native, or ${target_alias} for cross.
74# Set by top level Makefile.
75# ${with_multisrctop} = how many levels of multilibs there are in the source
76# tree. It exists to handle the case of configuring in the source tree:
77# ${srcdir} is not constant.
78# ${with_multisubdir} = name of multilib subdirectory (eg: m68020/m68881).
79#
80# Makefile variables:
81# MULTISRCTOP = number of multilib levels in source tree (+1 if cross)
82# (FIXME: note that this is different than ${with_multisrctop}. Check out.).
83# MULTIBUILDTOP = number of multilib levels in build tree
84# MULTIDIRS = list of multilib subdirs (eg: m68000 m68020 ...)
85# (only defined in each library's main Makefile).
86# MULTISUBDIR = installed subdirectory name with leading '/' (eg: /m68000)
87# (only defined in each multilib subdir).
88
89# FIXME: Multilib is currently disabled by default for everything other than
90# newlib. It is up to each target to turn on multilib support for the other
91# libraries as desired.
92
93# Autoconf incoming variables:
94# srcdir, host, ac_configure_args
95#
96# We *could* figure srcdir and host out, but we'd have to do work that
97# our caller has already done to figure them out and requiring these two
98# seems reasonable.
99# Note that `host' in this case is GCC's `target'. Target libraries are
