The block argument for store_block can be -1 when the tftp sequence number rolls over (i.e TftpBlock == 0), so the first argument to store_block has to be of type 'int' instead of 'unsigned'. In our environment (gcc 4.4.5 mips toolchain), this causes incorrect 'offset' to be generated for storing the block, and the tftp block with number 0 will be written elsewhere, resulting in a bad block in the downloaded file and a memory corruption.
