The configuration of less supports many different regex libraries. I
downloaded the source and ran "./configure --with-regex=pcre" and
built a nice version of less that fully supports \b and the various
other perl regex extensions. The output of cygwin's standard "less
--version" indicates it was compiled with posix regex, while linux
suppliers seem to all use gnu regex (which also supports various
perl-isms these days).
I think it would be nice to tweak the less package to be compiled with
pcre regex.
