Linking problems...

Hi,

I have a little problem with linking a sample application using bbv2, VC7.1.
I got unresolved external symbols for some system library stuff.

E.g.
msvc.link example\MDIWindow\bin\msvc\release\MDIWindow.exe example\MDIWindow\bin\msvc\release\MDIWindow.rsp
ZincT.lib(w_winmgr.obj) : error LNK2019: unresolved external symbol __imp__GetWindowLongA_at_8 referenced in function "public: static class ZafWindowObject * __cdecl ZafMSWindowsApp::ObjectFromHandle(struct HWND__ *)" (?ObjectFromHandle_at_ZafMSWindowsApp@@SAPAVZafWindowObject@@PAUHWND__@@@Z)

How can I link to these system libraries?
Using makefiles I always listed them. I this what I also have to do with bbv2?

My root jam file:

My example jam file:

build-project MDIWindow ;

My MDIWindow jam file:
----------------------------------
project MDIWindow ;

exe MDIWindow : MDIWIN.cxx /znc//ZincT ;

Another questen: Building the Zinc lib I got the following warnings: I don't understand what I'm doing wrong.

warning: using independent target <pznc\bin\msvc\release\link-static>Zinc.rsp
msvc.archive znc\bin\msvc\release\link-static\Zinc.lib znc\bin\msvc\release\link-static\Zinc.rsp
