* sysdeps/mips/jmpbuf-unwind.h (_JMPBUF_CFA_UNWINDS_ADJ): Cast
_Unwind_GetCFA return to _Unwind_Ptr before casting to a pointer
type.
* sysdeps/unix/sysv/linux/mips/____longjmp_chk.c (CHECK_SP): Cast
ss_sp to long before casting to sp_type.
* sysdeps/unix/sysv/linux/mips/sigcontextinfo.h [_MIPS_SIM ==
_ABIO32] (GET_PC): Cast to unsigned long before casting to a
pointer type.
[_MIPS_SIM == _ABIO32] (GET_FRAME): Likewise.
[_MIPS_SIM == _ABIO32] (GET_STACK): Likewise.
[_MIPS_SIM != _ABIO32] (GET_PC): Likewise.
[_MIPS_SIM != _ABIO32] (GET_FRAME): Likewise.
[_MIPS_SIM != _ABIO32] (GET_STACK): Likewise.
* sysdeps/mips/bits/atomic.h [!__GNUC_PREREQ (4, 8)]
(__arch_compare_and_exchange_xxx_8_int): Separate assignments to
__prev and __cmp. Cast __cmp to void.
