[pcre-dev] Patch for NO_RECURSE and Visual Studio Build

Hello,

I'm a dev of the XBMC project (see http://xbmc.org/). We use libpcre in
the media scrapers, to process the html returned by sites such as
imdb.com and extract fields like the movie title, year, plot, etc.

We decided to define NO_RECURSE and had to add a couple casts to build
pcre under Visual Studio.
You will find attached the patch. Please consider merging it in the
official source code.

Regards,

Pierre
