* coffread.c (coff_end_symtab): Cast 2nd arg of complain() to correct type. * defs.h (NORETURN): Define away for Lucid compiler. * remote.c (remote_timer, remote_interrupt): Signal handlers take one int arg. * ser-termios.c (serial_write, serial_close): Return whatever value the write/close call returns, rather than falling off end. * inferior.h (PTRACE_ARG3_TYPE): Third arg to ptrace is int on more systems than it is "char *". Define PTRACE_ARG3_TYPE to default to int. * infptrace.c, hppabsd-xdep.c, hppahpux-xdep.c, i386-xdep.c, inferior.h (call_ptrace): Use PTRACE_ARG3_TYPE to declare type of third arg. * a68v-xdep.c, arm-xdep.c, convex-xdep.c, hp300ux-xdep.c, infrun.c, m88k-xdep.c, mach386-xdep.c, mips-xdep.c, os68k-xdep.c, pyr-tdep.c, pyr-xdep.c, rs6000-xdep.c, sparc-xdep.c, sun3-xdep.c, sun386-xdep.c, symm-xdep.c, ultra3-xdep.c: Use PTRACE_ARG3_TYPE to cast ptrace argument 3. * sparc-xdep.c, a68v-xdep.c (fetch_inferior_registers, store_inferior_registers): Supply missing fourth argument to ptrace().
