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.

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