On the second thought, could it be that man page & binary are out of
sync for some reason?  It is hard to believe though as -C option
parsing appears in src/usr.bin/make/main.c, line 185...

  178  #ifdef REMOTE
  179  # define OPTFLAGS "BD:E:I:L:PSV:Xd:ef:ij:km:nqrstv"
  180  #else
  181  # define OPTFLAGS "BD:E:I:PSV:Xd:ef:ij:km:nqrstv"
  182  #endif
  183  rearg:  while((c = getopt(argc, argv, OPTFLAGS)) != -1) {
  184                  switch(c) {
  185                  case 'C':
  186                          if (chdir(optarg) == -1)
  187                                  err(1, "chdir %s", optarg);
  188                          break;


...but is omitted from OPTFLAGS (lines 179 & 181).  Is that the reason
of make carping when presented w/ -C option?
