94 | # depending on how configure is run. This is pretty annoying, since

---|
104 | # a relative $ac_aux_dir
|
---|
105 | #
|
---|
106 | # The reason of the latter failure is that $top_srcdir and $ac_aux_dir
|
---|
107 | # are both prefixed by $srcdir. In an in-source build this is usually
|
---|
108 | # harmless because $srcdir is '.', but things will broke when you
|

109 | # start a VPATH build or use an absolute $srcdir.

110 | #

111 | # So we could use something similar to $top_srcdir/$ac_aux_dir/missing,

|
---|
113 | # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
