1046 # Of course, Automake must honor this variable whenever it calls a

1049 # depending on how configure is run. This is pretty annoying, since
1050 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
1051 # source directory, any form will work fine, but in subdirectories a
1052 # relative path needs to be adjusted first.

1058 # fails when called from a subdirectory in a VPATH build with
1059 # a relative $ac_aux_dir
1061 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
1062 # are both prefixed by $srcdir. In an in-source build this is usually
1063 # harmless because $srcdir is `.', but things will broke when you
1064 # start a VPATH build or use an absolute $srcdir.
1066 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
1067 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
1068 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
1069 # and then we would define $MISSING as
1070 # MISSING="\${SHELL} $am_aux_dir/missing"
1071 # This will work as long as MISSING is not called from configure, because
