From 8b8948c06de55455b63dc11f765d7ee39f30c4e0 Mon Sep 17 00:00:00 2001

Subject: [PATCH 03/14] mkfs.fat.c: Use unsigned char for binary data

Simple char technically works for the dummy_boot_jump variables, but
some compiler warning settings would give a warning over a signed char
overflowing with the values given as initializers.
