     61 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
     62 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
     63 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
     64 #
     65 # Of course, Automake must honor this variable whenever it calls a
     66 # tool from the auxiliary directory.  The problem is that $srcdir (and
     67 # therefore $ac_aux_dir as well) can be either absolute or relative,
     68 # depending on how configure is run.  This is pretty annoying, since
     69 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
     70 # source directory, any form will work fine, but in subdirectories a
     71 # relative path needs to be adjusted first.
     72 #
     73 # $ac_aux_dir/missing
     74 #    fails when called from a subdirectory if $ac_aux_dir is relative
     75 # $top_srcdir/$ac_aux_dir/missing
     76 #    fails if $ac_aux_dir is absolute,
     77 #    fails when called from a subdirectory in a VPATH build with
     78 #          a relative $ac_aux_dir
     79 #
     80 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
     81 # are both prefixed by $srcdir.  In an in-source build this is usually
     82 # harmless because $srcdir is `.', but things will broke when you
     83 # start a VPATH build or use an absolute $srcdir.
     84 #
     85 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
     86 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
     87 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
     88 # and then we would define $MISSING as
     89 #   MISSING="\${SHELL} $am_aux_dir/missing"
     90 # This will work as long as MISSING is not called from configure, because
     91 # unfortunately $(top_srcdir) has no meaning in configure.
     92 # However there are other variables, like CC, which are often used in
     93 # configure, and could therefore not use this "fixed" $ac_aux_dir.
     94 #
     95 # Another solution, used here, is to always expand $ac_aux_dir to an
     96 # absolute PATH.  The drawback is that using absolute paths prevent a
     97 # configured tree to be moved without reconfiguration.

    424 # is unlikely to handle the host's binaries.
    425 # Fortunately install-sh will honor a STRIPPROG variable, so we
