metachar in awk 3.1.3 under cygwin

Hello,

Please I'm trying to enter [ square left bracket in a regular expression
with awk 3.1.3 under cygwin. I use \[ but the system says :

warning: escape sequence '\[' treated as plain '['

how can I enter '[' in regular expression.

Thank you.

Hmmmm.

% gawk '/\[/'
foo[bar
foo[bar
foo
% gawk '/[/'
gawk: cmd. line:1: /[/
gawk: cmd. line:1:  ^ unterminated regexp
gawk: cmd. line:2: /[/
gawk: cmd. line:2:    ^ unexpected newline
%

Seems OK to me (Unix, tcsh, gawk 3.1.3).
