offset is long while EMUFILE size/location are uint32_t, so the SEEK_SET and SEEK_CUR bounds checks mixed signed and unsigned operands. Cast to uint32_t for the comparisons, but first reject the cases a bare cast would silently wrap: a negative SEEK_SET offset, and a SEEK_CUR rewind past the start. Behaviour for valid seeks is unchanged; invalid negative seeks now fail cleanly instead of wrapping to a huge offset.
