us up to version 2.17.50.20070703, at the last GPLv2 commit. Amongst others, this added upstream support for some FreeBSD-specific things that we previously had to manually hack in, such as the OSABI label support, and so on. There are also quite a number of new files, some for cpu's (e.g. SPU) that we may or may not be interested in, but those can be cleaned up later on, if needed.

# It is advisable to support a few --enable/--disable options to let the

# Subdirectories wishing to use multilib should put the following lines
|
|
# in the "post-target" section of configure.in.
|
|
#
|

# if [ "${srcdir}" = "." ] ; then

# . ${with_multisrctop}../../config-ml.in

# 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).
|
|
|
|
