47 # Things are complicated because 6 separate cases must be handled:
48 # 2 (native, cross) x 3 (absolute-path, relative-not-dot, dot) = 6.
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
54 # The build tree is layed out as
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=.
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.

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).
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
