3 # Configuration subroutine to validate and canonicalize a configuration type.
4 # Supply the specified configuration type as an argument.
5 # If it is invalid, we print an error message on stderr and exit with code 1.
6 # Otherwise, we print the canonical config type on stdout and succeed.
8 # This file is supposed to be the same for all GNU packages
9 # and recognize all the CPU types, system types and aliases
10 # that are meaningful with *any* GNU software.
11 # Each package is responsible for reporting which valid configurations
12 # it does not support. The user should be able to distinguish
13 # a failure to support a valid configuration from a meaningless
14 # configuration (e.g. a typo).
16 # Please email any bugs, comments, and/or additions to this file to:
17 # configure@cygnus.com
19 # decode aliases into canonical names
22 # cpu alone is a valid alias for cpu-none-none.
