workaround for ${1+"$@"}.
* doc/autoconf.texi (Shell Substitutions): Explain it.
From Oliver Kiddle and Peter Stephenson.
Have M4sh perform minimal shell sanitizing.
* lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
part into...
(_AS_PREPARE): this new macro.
(AS_PREPARE): New.
(AS_INIT): Invoke AS_SHELL_SANITIZE.
* tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
Adjust Autoconf and Autotest.
* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
* lib/autotest/general.m4 (AT_INIT): Likewise.
* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
Invoke _AS_PREPARE (not AS_PREPARE) in addition to
AS_SHELL_SANITIZE.
Use this M4sh to generate Autoconf's shell scripts.
* tests/wrapsh.as: New, precursor of wrapsh.in.
* tests/Makefile.am: Include lib/freeze.mk to get the dependencies
on Autotest and M4sh.
($(TESTSUITE)): Use $(autotest_m4f_dependencies).
(wrapsh.in): New target.
* bin/autoconf.as: New, precursor of autoconf.in.
(autoconf.in): New target.

.SH NAME
|
|
config.guess \- guess the build system triplet
|
|
.SH SYNOPSIS
|
|
.B config.guess
|
|
[\fIOPTION\fR]
|
|
.SH 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.
|
|
.PP
|
|
Output the configuration name of the system `config.guess' is run on.

|
.SH "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
|
|
