Bug#222878: Header incompatibilities

[Dale Amon <amon@vnl.com>]

I was asking elsewhere and got directed here. FWIW, here's
what I tracked down:

I've used source both from upstream and via apt-get. The
only thing that changes is in which .c the error shows
up first. The below is from upstream sourceL

cc -pipe -O2 -mcpu=i486 -fomit-frame-pointer -I../lib -Wall -Wmissing-prototype\

make[1]: *** [blockdev] Error 1
make[1]: Leaving directory `/dma/Sbuilder2/Obj-mourne/util-linux-2.12/disk-utils'
make: *** [all] Error 1


There are actually only 3 errors; the rest are just
caused by them:

        blockdev.c:70: error: parse error before '[' token
        blockdev.c:73: error: parse error before '[' token
        blockdev.c:331: error: parse error before '[' token

I narrowed things down by doing a macro expansion. blockdev.c
line 70 contains this:

#ifdef BLKSSZGET
        { "--getss", "BLKSSZGET", BLKSSZGET, ARGINTG, -1, NULL, N_("get sectors\
ize") },
#endif

which macro expands to this:
        { "--getbsz", "BLKBSZGET", (((2U) << (((0 +8)+8)+14)) | (((0x12)) << (0\
 +8)) | (((112)) << 0) |
+(((((sizeof(sizeof(int)) == sizeof(sizeof(int)[1]) && sizeof(sizeof(int)) < (1\
 << 14)) ? sizeof(sizeof(int)) :
+__invalid_size_argument_for_IOC))) << ((0 +8)+8))), 4, -1, ((void *)0), ("get \
blocksize") },

If you look closely you will see sizeoff(int)[1]. That
is the error which occurs in all three lines here (and
also once in get_blocks.c.

Appears to happen in _IOR and _IOW macros.
