The most common use # of this is to update config.guess and config.sub when configure dies from # misguessing your canonical system name (CHOST). It can also be used to update # 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. # All files in the source tree ($S) with the given name(s) will be replaced # with the newest available versions chosen from the list of locations in # gnuconfig_findnewest(), below.
