--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
It's -mms-bitfields which appearantly influences layout of the following
struct:
union {
unsigned char raw[8];
struct {
uint8_t gz_method;
uint8_t flags;
uint32_t mtime;
uint8_t xtra_flags_UNUSED;
uint8_t os_flags_UNUSED;
} __attribute__ ((__packed__)) formatted;
} header;
((void)sizeof(char[1 - 2*!!(sizeof(header) != 8)]));
Not sure if the difference is intended.
