/usr/include/X11/extensions/XIproto.h contains reserved C++ keyword

The file /usr/include/X11/extensions/XIproto.h cannot be included from C++ programs as it contains the reserved "delete" keyword.

This happens for example when compiling toolkits, such as Qt.

The offending code in question:

typedef struct {
    CARD8 reqType; /* input extension major opcode */
    CARD8 ReqType; /* always X_ChangeDeviceProperty */
    CARD16 length B16;
    Atom property B32;
    Atom type B32;
    CARD32 longOffset B32;
    CARD32 longLength B32;
    CARD8 deviceid;
    BOOL delete;
    CARD16 pad;
} xGetDevicePropertyReq;
