Then you're most likely accidentally using DMD's link.exe. When 
using a multilib LDC build on Win64 and cross-compiling to Win32, 
the IMO simplest way is to spawn a new naked cmd.exe shell with 
untainted PATH and let LDC detect the Visual Studio installation 
(and the 32-bit lib dirs).

On my system:

extern (Windows) int WinMain() { return 0; }

ldc2 -L/SUBSYSTEM:WINDOWS -m32:
error LNK2019: unresolved external symbol _WinMain at 16 referenced 
in function "int __cdecl __scrt_common_main_seh(void)" 
(?__scrt_common_main_seh@@YAHXZ)

It's working with proper signature [1]:

extern (Windows) int WinMain(void* hInstance, void* 
hPrevInstance, void* lpCmdLine, int nCmdShow) { return 0; }
