* infptrace.c: Split out define of PT_KILL; Sequent defines PT_KILL
but not the others. * symm-tdep.c: Remove exec_file_command. [_SEQUENT_] (ptx_coff_regno_to_gdb, register_addr): New functions. A few miscellaneous cleanups. * symm-nat.c: Renamed from symm-xdep.c. * All symmetry dependent files: Many changes.
