I solved it so:
asm/ioctl.h:
...............
/* used to create numbers */
#define _IO(type,nr)            _IOC(_IOC_NONE,(type),(nr),0)
#define _IOR(type,nr,size)      
_IOC(_IOC_READ,(type),(nr),(_IOC_TYPECHECK(size)))
#define _IOW(type,nr,size)      
_IOC(_IOC_WRITE,(type),(nr),(_IOC_TYPECHECK(size)))
#define _IOWR(type,nr,size)     
_IOC(_IOC_READ|_IOC_WRITE,(type),(nr),(_IOC_TYPECHECK(size)))
#define _IOR_BAD(type,nr,size)  _IOC(_IOC_READ,(type),(nr),sizeof(size))
#define _IOW_BAD(type,nr,size)  _IOC(_IOC_WRITE,(type),(nr),sizeof(size))
#define _IOWR_BAD(type,nr,size) 
_IOC(_IOC_READ|_IOC_WRITE,(type),(nr),sizeof(size))
.....................
I patched all files that contains next defines:
_IOR, _IOW or _IOWR
with
_IOR_BAD, _IOW_BAD, _IOWR_BAD

Really it is not right. 
But it would be so if I complie with 2.4.x headers

sizeof(sizeof(anymore)) is sizeof(int). And threre was int. Thus it was right 
only there.
