2089 # Of course, Automake must honor this variable whenever it calls a

2091 # therefore $ac_aux_dir as well) can be either absolute or relative,
2092 # depending on how configure is run. This is pretty annoying, since
2093 # it makes $ac_aux_dir quite unusable in subdirectories: in the top
2094 # source directory, any form will work fine, but in subdirectories a
2095 # relative path needs to be adjusted first.
2097 # $ac_aux_dir/missing
2098 # fails when called from a subdirectory if $ac_aux_dir is relative

2100 # fails if $ac_aux_dir is absolute,
2101 # fails when called from a subdirectory in a VPATH build with
2102 # a relative $ac_aux_dir
2104 # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
2105 # are both prefixed by $srcdir. In an in-source build this is usually
2106 # harmless because $srcdir is `.', but things will broke when you
2107 # start a VPATH build or use an absolute $srcdir.
2109 # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
2110 # iff we strip the leading $srcdir from $ac_aux_dir. That would be:
2111 # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
2112 # and then we would define $MISSING as
2113 # MISSING="\${SHELL} $am_aux_dir/missing"
2114 # This will work as long as MISSING is not called from configure, because
2115 # unfortunately $(top_srcdir) has no meaning in configure.
2116 # However there are other variables, like CC, which are often used in
2117 # configure, and could therefore not use this "fixed" $ac_aux_dir.
