I'm not sure why it is not working either. It "ought" to work. You can probably see the alister and hanson44 solutions are the same, the only difference being whether to assign the pattern to a separate variable.
To figure out why it is not working, post what you are doing, how you are trying to implement the solution, and what the output is. It will help if you can post more than a fragment, post something that produces output, something we can replicate. And post what version of awk is being used in your cygwin environment, which might make a difference.
awk --version will probably print the version. If not, figure out what the awk version is however you can.

English(3pm) Perl Programmers Reference Guide English(3pm)
NAME
English - use nice English (or awk) names for ugly punctuation variables
SYNOPSIS
use English;
use English qw( -no_match_vars ) ; # Avoids regex performance penalty
# in perl 5.16 and earlier
...
if ($ERRNO =~ /denied/) { ... }
DESCRIPTION
This module provides aliases for the built-in variables whose names no one seems to like to read. Variables with side-effects which get
triggered just by accessing them (like $0) will still be affected.
For those variables that have an awk version, both long and short English alternatives are provided. For example, the $/ variable can be
referred to either $RS or $INPUT_RECORD_SEPARATOR if you are using the English module.
See perlvar for a complete list of these.
PERFORMANCE
NOTE: This was fixed in perl 5.20. Mentioning these three variables no longer makes a speed difference. This section still applies if
your code is to run on perl 5.18 or earlier.
This module can provoke sizeable inefficiencies for regular expressions, due to unfortunate implementation details. If performance matters
in your application and you don't need $PREMATCH, $MATCH, or $POSTMATCH, try doing
use English qw( -no_match_vars ) ;
. It is especially important to do this in modules to avoid penalizing all applications which use them.
