PROBLEM: 2.6.0-test5: ioctl.h: _IOC_TYPECHECK: Is it a bug?

[Sinelnikov Evgeny <linux4sin@mail.ru>]

Hello!
I have problem with linux-utils.2.12 compile on 2.6.0-test5 headers. From this 
version instead 2.6.0-test4 was changed next file where added next string:

include/asm-i386/ioctl.h:
#define _IOC_TYPECHECK(t) \
        ((sizeof(t) == sizeof(t[1]) && \
          sizeof(t) < (1 << _IOC_SIZEBITS)) ? \
          sizeof(t) : __invalid_size_argument_for_IOC)

This string have problems with compiling files using _IOR macros from ioctl.h
Here is example from util-linux-2.12:
#define BLKBSZGET  _IOR(0x12,112,sizeof(int))
ioctl (fd, BLKBSZGET, &bsz) == 0
After precompiling looking like this:
ioctl (fd, (((2U) << (((0 +8)+8)+14)) | (((0x12)) << (0 +8)) | (((112)) << 0) 
| (((((sizeof(sizeof(int)) == size
of(sizeof(int)[1]) && sizeof(sizeof(int)) < (1 << 14)) ? sizeof(sizeof(int)) : 
__invalid_size_argument_for_IOC))) << ((0 +8)
+8))), &bsz) == 0

Is it a bug or new feature? May be this is a bug of package?
