parted fat bug on ARM platform

[Lennert Buytenhek]

(please CC, not on the list.)

Hi all,

Compiling parted 1.6.15 for ARM (armv4b) seems to work, but on
startup it says:

        A bug has been detected in GNU parted.  Please email a bug
        report to address@hidden containing the version (1.6.15)
        and the following message:GNU parted was miscompiled: the FAT
        boot sector should be 512 bytes.  FAT support will be disabled.

This patch fixes that.  Note that even with this patch, unaligned
accesses are not guaranteed to work on the ARM ("anything can happen",
an unaligned read can return any value including garbage), so you
can still trash your file systems if you're not careful.


cheers,
Lennert
