 in mutex.inl:

 if (HMODULE kernel_module = GetModuleHandle(TEXT("KERNEL32.DLL")))
    g_TryEnterCriticalSection =
 reinterpret_cast<TryEnterCriticalSection_type>(GetProcAddress(kernel_module,
 TEXT("TryEnterCriticalSection")));

 The problem is that GetProcAddress() on windows only has ascii version
 and takes lpcstr as the name of the function to lookup, so if you
 define UNICODE to do windows unicode build, compiler complains that
 you're trying to pass WCHAR* as char*.

 A complication here is with wince, which is the opposite and only
 takes WCHAR* as the name of the function so the correct code should
 pass "TryEnterCriticalSection" on non-wince and
 L"TryEnterCriticalSection" on wince.
