Yes, QDir does need it. The enum Sortspec contains an entry "Unsorted"
(l. 80 in qdir.h from qt 3.2.3).
X.h (from XFree86 4.3.0) also defines Unsorted, at least on Debian:
/* SetClipRectangles ordering */

#define Unsorted                0
#define YSorted                 1
#define YXSorted                2
#define YXBanded                3

I needed a lot of time to figure out why g++ refused to compile, error 
message was "Error while parsing numeric constant", until I looked into 
the cpp output, where
Unsorted = 0x03,
was preprocessed to
0 = 0x03,

Sorry, I was not clear enough. The problem are the following to 
functions of KShortcutList:

     virtual const KShortcut& shortcut (uint) const = 0;
     virtual const KShortcut& shortcutDefault (uint) const = 0;

They are abstract, thus sipKShortcutList::shortcut(...) and 
KShortcutList::shortcutDefault(...) try to create a new instance of 
KShortcut if no Python method is defined, since they cannot call a class 
method in KShortcutList. The problem is that they create it with
if(!meth)
	return *new const KShortcut&();
which fails to compile, it complains that it is not possible to create a 
simple type with new.
The affedted lines are 51336 and 51351 in sipkdecorepart0.cpp generated 
by sip4.

Yes, it was this one.

I'm glad I can help!
