need for typedef Enum enum_type in qglobal.h

[jamadagni]

At line 1634 of qt-x11-opensource-src-4.2.3/src/corelib/global/qglobal.h we have:

typedef Enum enum_type;

typedef Enum enum_type;

To copy to clipboard, switch view to plain text mode 

but the word enum_type does not seem to be used anywhere in the QFlags class. Is this supposed to be a convenience? If yes, in what way? If no, an anyone tell me what this typedef is really used for?

Thanks.
