Subject: win32: Add missing header files for nginx compilation
The new ones are hoisted from mingw-w64 as most other headers under
`win32/include/winapi`

run4flat is a tcc fork by David Mertens that knows how to work with
multiple symbol tables. Excelent work. A good descriptions of the
tcc internals inside a code comments.
