     66 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
     67 # $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
     68 # `$srcdir', `$srcdir/..', or `$srcdir/../..'.
     69 #
     70 # Of course, Automake must honor this variable whenever it calls a
     71 # tool from the auxiliary directory.  The problem is that $srcdir (and
     72 # therefore $ac_aux_dir as well) can be either absolute or relative,
     73 # depending on how configure is run.  This is pretty annoying, since
     74 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
     75 # source directory, any form will work fine, but in subdirectories a
     76 # relative path needs to be adjusted first.
     77 #
     78 # $ac_aux_dir/missing
     79 #    fails when called from a subdirectory if $ac_aux_dir is relative
     80 # $top_srcdir/$ac_aux_dir/missing
     81 #    fails if $ac_aux_dir is absolute,
     82 #    fails when called from a subdirectory in a VPATH build with
     83 #          a relative $ac_aux_dir
     84 #
     85 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
     86 # are both prefixed by $srcdir.  In an in-source build this is usually
     87 # harmless because $srcdir is `.', but things will broke when you
     88 # start a VPATH build or use an absolute $srcdir.
     89 #
     90 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
     91 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
     92 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
     93 # and then we would define $MISSING as
     94 #   MISSING="\${SHELL} $am_aux_dir/missing"
     95 # This will work as long as MISSING is not called from configure, because
     96 # unfortunately $(top_srcdir) has no meaning in configure.
     97 # However there are other variables, like CC, which are often used in
     98 # configure, and could therefore not use this "fixed" $ac_aux_dir.
     99 #
    100 # Another solution, used here, is to always expand $ac_aux_dir to an
    101 # absolute PATH.  The drawback is that using absolute paths prevent a
    102 # configured tree to be moved without reconfiguration.
