unresolved external symbol _GetFileVersionInfoA@16

I have an application which includes a header file which define few
function from winver.h, such as GetFileVersionInfo and some others.
When I try to link the project, I get an error message, as described
in the subject. In the hearder file I have an include for "winver.h",
and I see it in the dependencies.
I am using NT4/WS and VC5++

Thanks,
Alon Weinberg
