 1037 # For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
 1038 # $ac_aux_dir to '$srcdir/foo'.  In other projects, it is set to
 1039 # '$srcdir', '$srcdir/..', or '$srcdir/../..'.
 1040 #
 1041 # Of course, Automake must honor this variable whenever it calls a
 1042 # tool from the auxiliary directory.  The problem is that $srcdir (and
 1043 # therefore $ac_aux_dir as well) can be either absolute or relative,
 1044 # depending on how configure is run.  This is pretty annoying, since
 1045 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
 1046 # source directory, any form will work fine, but in subdirectories a
 1047 # relative path needs to be adjusted first.
 1048 #
 1049 # $ac_aux_dir/missing
 1050 #    fails when called from a subdirectory if $ac_aux_dir is relative
 1051 # $top_srcdir/$ac_aux_dir/missing
 1052 #    fails if $ac_aux_dir is absolute,
 1053 #    fails when called from a subdirectory in a VPATH build with
 1054 #          a relative $ac_aux_dir
 1055 #
 1056 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
 1057 # are both prefixed by $srcdir.  In an in-source build this is usually
 1058 # harmless because $srcdir is '.', but things will broke when you
 1059 # start a VPATH build or use an absolute $srcdir.
 1060 #
 1061 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
 1062 # iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
 1063 #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
 1064 # and then we would define $MISSING as
 1065 #   MISSING="\${SHELL} $am_aux_dir/missing"
 1066 # This will work as long as MISSING is not called from configure, because
 1067 # unfortunately $(top_srcdir) has no meaning in configure.
 1068 # However there are other variables, like CC, which are often used in
 1069 # configure, and could therefore not use this "fixed" $ac_aux_dir.
 1070 #
 1071 # Another solution, used here, is to always expand $ac_aux_dir to an
 1072 # absolute PATH.  The drawback is that using absolute paths prevent a
