Let's create a disk with 33553920 bytes optimal I/O size:

Kay reported that Windows 8.1 installed does not recognize GPT created

It seems (according to the header hexdump) that the problem is
HeaderSize GPT field where libfdisk uses 512 (header + reserved area),
but parted uses 92. The both is pretty valid according to the current
EFI standard, but 92 is probably more backwardly compatible.
I also found places in code where libfdisk gpt driver is inconsistent
and uses sometimes all sector and simetimes sizeof(gpt_header) only.
The right solution is to read all sector (into zeroized memory) and
later write again all sector to the device.

order of the columns etc. Now it will be possible to do the same with
fdisk.
And it's also possible to use FDISK_COL_* Ids to address data, for
example:
fdisk_partition_get_data(cxt, FDISK_COL_SIZE, 1, &data);
returns a string with human readable size (<num>{MGT}) of the second
partition.

The _DEPENDENCIES has to be used for dependencies on another in-tree
files, but _LIBADD is to specify additional libs (including external
libs).

fdisk allows to overwrite existing partition if the partition has
partition type set to zero (very unusual, but possible).
This is incorrect because such partition is pretty valid (and Linux
kernel does not care about the type at all). For example:
Device Boot Start End Blocks Id System
/dev/sdb1 2048 22527 10240 83 Linux
/dev/sdb2 22528 227327 102400 0 Empty
^^^^^ ^^^^^^^^
Command (m for help): n
Partition type:
p primary (1 primary, 0 extended, 3 free)
e extended
Select (default p):
Using default response p
Partition number (3,4, default 3):
First sector (22528-1228799, default 22528):
^^^^^^^
.. if user follows the default then the result are overlapping
partitions:
Device Boot Start End Blocks Id System
/dev/sdb1 2048 22527 10240 83 Linux
/dev/sdb2 22528 227327 102400 0 Empty
/dev/sdb3 22528 1228799 603136 83 Linux
^^^^^
... and if you call "mkfs /dev/sdb3" then you lost data on sdb2. Sad
thing.

The SGI drive currently counts only usable partitions, that's wrong as
Linux kernel counts all partition to generate partition number. For
example:
Kernel:
sdb 8:16 0 600M 0 disk
├─sdb9 8:25 0 2M 0 part
└─sdb11 8:27 0 596.2M 0 part
Fdisk:
Pt# Device Info Start End Sectors Id System
9: /dev/sdb1 0 4095 4096 0 SGI volhdr
11: /dev/sdb2 0 1220939 1220940 6 SGI volume

Notes:
* fdisk don't sync hybrid MBR with GPT
* hybrid MBR is ignored and not overwritten by PBMR
* users is informed about expert command 'M' to toggle between MBR
and GPT mode. It's possible to manually modify hybrid MBR.

We already have all code to support this feature, unfortunately
it was not used in gpt_probe_label()...

Unfortunately, fdisk_warn/info/.. function was not marked by
printf __attribute__.
We don't want to break gettext stuff now, so all compiler warnings
have been fixed by casts. This is temporary solution, after release it
will be necessary to fix all the strings.

.. to make 'D'ump expert command usable also for MBR.
Yes, we have -rc2 now and this is a new feature, but it's tiny change
without any interaction to the rest of the code and without gettext stuff.
