Type conflict between "tango.sys.SharedLib.BOOL" and "tango.sys.win32.Types.BOOL"

Description

I have a simple test case where I'm trying to load a DLL using the SharedLib? library, while using type aliases defined in the win32 Types module, and the compiler reports an ambiguity between "tango.sys.SharedLib?.BOOL" and "tango.sys.win32.Types.BOOL".

The simple test case is: 

import tango.sys.SharedLib;
import tango.sys.win32.Types;

struct MEMORYSTATUSEX
{
   DWORD dwLength;
   DWORD dwMemoryLoad;
   DWORDLONG ullTotalPhys;
   DWORDLONG ullAvailPhys;
   DWORDLONG ullTotalPageFile;
   DWORDLONG ullAvailPageFile;
   DWORDLONG ullTotalVirtual;
   DWORDLONG ullAvailVirtual;
   DWORDLONG ullAvailExtendedVirtual;
}

void main() {
  auto lib = SharedLib.load(`c:\windows\system32\kernel32.dll`);
  void* exFunctionPtr = lib.getSymbol("GlobalMemoryStatusEx");
  if (exFunctionPtr) {
    auto fnptr = cast(BOOL function(MEMORYSTATUSEX)) exFunctionPtr;
  }
}

Compiling with "dsss build", I get the following message: 

typetest.d => typetest
+ D:\Development\d\libs\dsss\bin\rebuild.exe -Idsss_imports\ -I. -S.\ -ID:\Development\d\libs\dsss\include\d -SD:\Development\d\libs\dsss\lib\  -ID:\Development\d\libs\dsss\include\d -SD:\Development\d\libs\dsss\lib  -oqdsss_objs\D  typetest.d -oftypetest

yeah, SharedLib? shouldn't have its own version of BOOL
