Gcc complains:
vhd-util-check.c: In function ‘vhd_util_check_footer’:
vhd-util-check.c:413:2: error: ‘buf’ may be used uninitialized in this function
[-Werror=maybe-uninitialized]
memcpy(&backup, buf, sizeof(backup));
In fact buf is initialised a few lines above.

I can't figure out why buf may be uninitialised and this seems to be the
only way to convince gcc it is ok to proceed.
