Current behaviour is completely correct. Nevertheless I fixed this spurious warning.

In tar.gz of 1.99rc2 version:
At grub-core/partmap/acorn.c:74
a for-loop tries to access 0x1ff elements in an array
(boot.misc) which has only 0x1c0.
(See grub_acorn_boot_block at the beginning of the same file.)

(Found with cppcheck 1.47.)

I do not know what is the expected behavior of this code-fragments but I am quite sure that this is a serious bug.
