First, I want to say that U++ compiles very well when used with MinGW 4.7 even when using c++11 compiler option for U++'s native libraries. But there are some issues pertaining to compilation.

To resolve these issues I've had to do the following changes:

1. Right before inclusion of the <shlobj.h> file, the CY definition must be undefined:

#undef CY
#include <shlobj.h>

I found two files that need to be fixes this way: App.cpp and Path.cpp

2. WINVER definition must be corrected in <Core.h>:
from
#ifdef COMPILER_MINGW
#define WINVER 0xFFFF
#endif

to
#if defined(COMPILER_MINGW) && !defined(WINVER)
#define WINVER 0xFFFF
#endif

3. The compiler asks to include <winsock2.h> before <windows.h>, so the definition block with <winsock2.h> need to be placed higher than the first <windows.h> inclusion in the <Core.h> file.

4. The line in the App.cpp source file must be chaged:
from
if (int(ShellExecuteW(NULL, L"open", wurl, NULL, L".", SW_SHOWDEFAULT)) <= 32) {

to
if (reinterpret_cast<std::ptrdiff_t>(ShellExecuteW(NULL, L"open", wurl, NULL, L".", SW_SHOWDEFAULT)) <= 32) {

5. In the Defs.h header file, the code must be changed:
from
#ifdef PLATFORM_WIN32
inline bool IsNaN(double d) { return _isnan(d); }

to
#ifdef PLATFORM_WIN32
inline bool IsNaN(double d) { return std::isnan(d); }

So, if I make all these changes, the compilation goes smooth and fine even with c++11 compiler option.
