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).

config.guess
CONFIG.GUESS(1) User Commands CONFIG.GUESS(1)
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
