4 config.guess \- guess the build system triplet

6 [Environment variables]
7 config.guess might need to compile and run C code, hence it needs a
8 compiler for the `build' machine: use the environment variable
9 `CC_FOR_BUILD' to specify the compiler for the build machine.  If
10 `CC_FOR_BUILD' is not specified, `CC' will be used.  Be sure to
11 specify `CC_FOR_BUILD' is `CC' is a cross-compiler to the `host'
12 machine.
13 
14   CC_FOR_BUILD    a native C compiler, defaults to `cc'
15   CC              a native C compiler, the previous variable is preferred
16 
17 [description]
18 The GNU build system distinguishes three types of machines, the
19 `build' machine on which the compilers are run, the `host' machine
20 on which the package being built will run, and, exclusively when you
21 build a compiler, assembler etc., the `target' machine, for which the
22 compiler being built will produce code.
23 
24 This script will guess the type of the `build' machine.
