1044 # Of course, Automake must honor this variable whenever it calls a

1047 # depending on how configure is run. This is pretty annoying, since
1048 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
1049 # source directory, any form will work fine, but in subdirectories a
1050 # relative path needs to be adjusted first.

1055 # fails if $ac_aux_dir is absolute,
1056 # fails when called from a subdirectory in a VPATH build with
1057 # a relative $ac_aux_dir
1059 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
1060 # are both prefixed by $srcdir. In an in-source build this is usually
1061 # harmless because $srcdir is '.', but things will broke when you
1062 # start a VPATH build or use an absolute $srcdir.
1064 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

1066 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
1067 # and then we would define $MISSING as
1068 # MISSING="\${SHELL} $am_aux_dir/missing"
1069 # This will work as long as MISSING is not called from configure, because
1070 # unfortunately $(top_srcdir) has no meaning in configure.
1071 # However there are other variables, like CC, which are often used in
