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
