-// are a frequent source of conflicts (e.g., GetUserName).
-//
-// Remember, that most of the WIN32 API functions come in two variants,
-// an Unicode variant (e.g., GetUserNameA) and an ASCII variant (GetUserNameW).
-// There is also a macro (GetUserName) that's either defined to be the Unicode
-// name or the ASCII name, depending on whether the UNICODE macro is #define'd
-// or not. POCO always calls the Unicode functions directly.
-//
-// These macro definitions are a frequent case of problems and naming conflicts,
-// especially for C++ programmers. Say, you define a class with a member function named
-// GetUserName. Depending on whether "Poco/UnWindows.h" has been included by a particular
-// translation unit or not, this might be changed to GetUserNameA/GetUserNameW, or not.
-// While, due to naming conventions used, this is less of a problem in POCO, some
-// of the users of POCO might use a different naming convention where this can become
-// a problem.
-//
-// To disable the #undef's, compile POCO with the POCO_NO_UNWINDOWS macro #define'd.
