If it works with C but not C++, I suspect that C++ name decoration can
be the problem.  Try:

extern "C" {
#include <w3dblib.h>
}

in your .cpp file, to let the compiler know that the externals in the
library are really C, not C++.  Otherwise the C++ compiler will make
up a decorated name for the function in your .obj, which won't match
what the linker sees in the .lib.
