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,  exclu‐
       sively  when  you  build a compiler, assembler etc., the `target' machine, for which the com‐
       piler 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.

OPTIONS
       -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' if `CC' is a cross-compiler to the `host' machine.

         CC_FOR_BUILD    a native C compiler, defaults to `cc'
         CC              a native C compiler, CC_FOR_BUILD is preferred
