* mips-linux-nat.c (MAX_DEBUG_REGISTER): Move it earlier in the code. (PTRACE_SET_WATCH_REGS, enum pt_watch_style): Remove. (struct mips32_watch_regs, struct mips64_watch_regs): Remove. (struct pt_watch_regs): Likewise. [!PTRACE_GET_WATCH_REGS] (PTRACE_SET_WATCH_REGS): New macro. [!PTRACE_GET_WATCH_REGS] (enum pt_watch_style): New. [!PTRACE_GET_WATCH_REGS] (struct mips32_watch_regs): New. [!PTRACE_GET_WATCH_REGS] (struct mips64_watch_regs): New. [!PTRACE_GET_WATCH_REGS] (struct pt_watch_regs): New.
