   How about something like this?  PERL-like split syntax, and the ability
to split on several different characters simultaneously (but always on
whitespace).  As always, memory allocation rears its ugly head, but not
too badly.  Sample code:

  char *str = "foo bar.baz=5";
  int nargs;
  char **ptrs;
  char **subptrs;

  ptrs = fc_malloc(3 * sizeof(char *));
  nargs = split("=", str, strlen(str), ptrs, 3);
  if(nargs < 3) { err_msg(); }
  /* ptrs[0] = "foo", ptrs[1] = "bar.baz", ptrs[2] = "5" */

  subptrs = fc_malloc(2 * sizeof(char*));
  nargs = split(".", ptrs[1], strlen(ptrs[1]), subptrs, 2);
  if(nargs < 2) { err_msg2(); }
  /* subptrs[0] = "bar", subptrs[1] = "baz" */

  /* ... do stuff ... */
