#!/bin/sh

# Configuration subroutine to validate and canonicalize a configuration type.
# Supply the specified configuration type as an argument.
# If it is invalid, we print an error message on stderr and exit with code 1.
# Otherwise, we print the canonical config type on stdout and succeed.

# This file is supposed to be the same for all GNU packages
# and recognize all the CPU types, system types and aliases
# that are meaningful with *any* GNU software.
# Each package is responsible for reporting which valid configurations
# it does not support.  The user should be able to distinguish
# a failure to support a valid configuration from a meaningless
# configuration (e.g. a typo).

# Please email any bugs, comments, and/or additions to this file to:
# configure@cygnus.com

# decode aliases into canonical names
# Note that aliases MUST fit into 12 characters or less otherwise the
# install targets and subdir builds all die on machines that support
# only 14 char file names.  They die miserably on machines that rudely
# enforce the 14 character limit.

case "$1" in
# cpu alone is a valid alias for cpu-none-none.
