Yes. Variable Length Arrays is an ANSI C99 feature. But they are not supported under C++, neither under the previous C standard. Also, there is support for variable length arrays in many different compilers in the form of language extensions (like the GNU C extensions found in the GNU C compiler).

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 REPORTING BUGS
