    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?
