Using DLL

[Zarathustra]

I created lib file:
implib /s zlib.lib zlib.dll
and:
zlib.d
but when I tryed compile:
dmd main.d zlib.d zlib.lib
in main.d is import zlib.d
I got some errors:
 main.obj(main)
 Error 42: Symbol Undefined _D4zlib10deflateEndFPS4zlib8z_streamZi
main.obj(main)
 Error 42: Symbol Undefined _D4zlib7deflateFPS4zlib8z_streamiZi

--- errorlevel 9

I don't know what is wrong, that zlib isn't linked.
