while investigated an unrelated bug, i noticed that the latest snapshot
uploaded to debian fails with the following error:

gcc-4.4 -Idisk -I/home/seanius/grub2-1.98+20100602/disk -I/home/seanius/grub2-1.98+20100602/include -I. -I./include -Wall -W  -ffreestanding  -Os -DGRUB_MACHINE_EMU=1 -DMACHINE=X86_64_EMU -Wall -W -Wshadow -Wpointer-arith -Wmissing-prototypes                -Wundef -Wstrict-prototypes -g -fno-dwarf2-cfi-asm -m64 -fno-stack-protector -mno-stack-arg-probe -Werror -DGRUB_TARGET_NO_MODULES=1 -DUSE_ASCII_FAILBACK=1  -DGRUB_FILE=\"disk/usbms.c\" -MD -c -o usbms_mod-disk_usbms.o /home/seanius/grub2-1.98+20100602/disk/usbms.c

/home/seanius/grub2-1.98+20100602/disk/usbms.c:315: error: format ‘%02x’ expects type ‘unsigned int’, but argument 5 has type ‘grub_size_t’
/home/seanius/grub2-1.98+20100602/disk/usbms.c:333: error: format ‘%02x’ expects type ‘unsigned int’, but argument 5 has type ‘grub_size_t’
make[1]: *** [usbms_mod-disk_usbms.o] Error 1

the two lines in question are both debug printf type statements.
therefore, instead of doing something complicated to get the format
string to match with the size of grub_size_t (which i'm guessing could
vary based on the platform), i have created a patch that simply casts the
parameter in question as unsigned to match the format string instead (which
only shows two digits anyway).
