Hi Rich,

Recent versions of MS4W no longer use the regex library because of its
restrictive license, so we now use the PCRE library
(http://www.pcre.org/).  You can check your local MS4W build versions at
any time by reading your local install readme
(127.0.0.1/README_INSTALL.html#mapserver-build-environment).

It would be great if you could run your tests on Linux and Windows with
that same PCRE library.

Thank you for using MS4W.
