[Wine] How a patch is included in a wine version

[xekhz]

Hello ppl
In my wine usage experience, I got a patch from Lei Zhang, and i worked 100% in my app.
When will this patch be included in a wine version ? patch refers to http://bugs.winehq.org/show_bug.cgi?id=15543

another question,
Sometimes powerbuilder application search for system32/drivers/etc/{hosts,services} files

Can this be created when we execute winecfg ?
