12 The GNU build system distinguishes three types of machines, the `build'
13 machine on which the compilers are run, the `host' machine on which the
14 package being built will run, and, exclusively when you build a com‐
15 piler, assembler etc., the `target' machine, for which the compiler
16 being built will produce code.
17
18 This script will guess the type of the `build' machine.
19
20 Output the configuration name of the system `config.guess' is run on.
21
22 Operation modes:
23 -h, --help
24 print this help, then exit
25
26 -t, --time-stamp
27 print date of last modification, then exit
28
29 -v, --version
30 print version number, then exit
31
33 config.guess might need to compile and run C code, hence it needs a
34 compiler for the `build' machine: use the environment variable
35 `CC_FOR_BUILD' to specify the compiler for the build machine. If
36 `CC_FOR_BUILD' is not specified, `CC' will be used. Be sure to specify
37 `CC_FOR_BUILD' is `CC' is a cross-compiler to the `host' machine.
38
39 CC_FOR_BUILD a native C compiler, defaults to `cc'
40 CC a native C compiler, the previous variable is pre‐
41 ferred
