LGTM.

However I am not sure about the number extraction itself on AIX, maybe you could check this please ?


#!/bin/sh

COMPILER_VERSION_OUTPUT=`xlC -qversion 2>&1`

COMPILER_VERSION_NUMBER=`echo $COMPILER_VERSION_OUTPUT | sed -e 's/^.*Version: (@<:@1-9@:>@@<:@0-9.@:>@*).*$/\1/'`

echo $COMPILER_VERSION_OUTPUT
echo $COMPILER_VERSION_NUMBER


gives me
IBM XL C/C++ for AIX, V16.1.0 (5725-C72, 5765-J12) Version: 16.01.0000.0013
IBM XL C/C++ for AIX, V16.1.0 (5725-C72, 5765-J12) Version: 16.01.0000.0013

So I wonder does the version number extraction really work on AIX ?
