* coffread.c (init_stringtab): Fix bug where sizeof(long) != 4.
* gdbcore.h, core.c (read_memory_unsigned_integer): New function. * findvar.c (read_register, write_register): Fix thinko where sizeof(host long) != sizeof(target int). * h8300-tdep.c: Use new read_memory_unsigned_integer call. * sh-tdep.c (_initialize_sh_tdep): Add memory_size command.
