| 198 | #          a relative $ac_aux_dir | 
|---|
| 199 | # | 
|---|
| 200 | # The reason of the latter failure is that $top_srcdir and $ac_aux_dir | 
|---|
| 201 | # are both prefixed by $srcdir.  In an in-source build this is usually |

|---|
| 207 | #   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` |
