# automake to the newest version available on the system. The most common use |
| 9 |
|
|
# of this is to update config.guess and config.sub when configure dies from |
| 10 |
|
|
# misguessing your canonical system name (CHOST). It can also be used to update |
| 11 |
|
|
# other files that come with automake, e.g. depcomp, mkinstalldirs, etc. |

|
# usage: gnuconfig_update [file1 file2 ...] |

|

# if called without arguments, config.guess and config.sub will be updated. |
