| 82 | #·source·directory,·any·form·will·work·fine,·but·in·subdirectories·a |

| 90 | #··········a·relative·$ac_aux_dir |
| 91 | # |
| 92 | #·The·reason·of·the·latter·failure·is·that·$top_srcdir·and·$ac_aux_dir |
| 93 | #·are·both·prefixed·by·$srcdir.··In·an·in-source·build·this·is·usually |

| 95 | #·start·a·VPATH·build·or·use·an·absolute·$srcdir. |
