You'll end up with /opt/wine/bin, /opt/wine/lib, etc? wine won't be in the path, which is not standard at all and will lead to "I can't use it after installation"...
Also, why do you force --with-nptl at the beginning? You'll get it either twice, or once if you don't need it.
D'oh, because I'm a fool and forgot that I modified my own copy of wineinstall locally. Here is the correct patch.
