In svn, configure script is located in auto/configure.  You may 
run as ./auto/configure.  Note there are also other minor layout 
differences from release tarballs (e.g.  building manpage will 
fail).

There are no win32-related files in release tarballs.

Right now the only person who knows how to correctly compile 
native nginx for Windows is Igor, and in the message you've 
referenced he clearly states that he isn't going to support 
building procedure.

I was able to compile nginx binary using a combination of MSYS 
environment from MinGW and Visual C compiler, with something like 
this:

./auto/configure --with-cc="cl" --without-http_rewrite_module --without-http_gzip_module
nmake

No idea how it works though.

Attached patch shuts up some warnings as shown by msvc.
