config.guess - guess the build system triplet

NAME
config.guess - guess the build system triplet

SYNOPSIS
config.guess [OPTION]

DESCRIPTION
The GNU build system distinguishes three types of machines,
the 'build' machine on which the compilers are
run, the 'host' machine on which the package being built will
run, and, exclusively when you build a compiler,
assembler etc., the 'target' machine, for which the compiler
being built will produce code.

This script will guess the type of the 'build' machine.

Output the configuration name of the system 'config.guess' is run on.

Operation modes:
-h, --help
print this help, then exit

-t, --time-stamp
print date of last modification, then exit

-v, --version
print version number, then exit

ENVIRONMENT VARIABLES
config.guess might need to compile and run C code, hence it
needs a compiler for the 'build' machine: use the
environment variable 'CC_FOR_BUILD' to specify the compiler for
the build machine. If 'CC_FOR_BUILD' is not
specified, 'CC' will be used. Be sure to specify
'CC_FOR_BUILD' is 'CC' is a cross-compiler to the 'host'
machine.

CC_FOR_BUILD a native C compiler, defaults to 'cc'
CC a native C compiler, the previous variable is preferred
