I think you can simplify this by eliminating the second part and changing the 
first part to the following:

         char sep = dir[strlen (dir) - 1];
         if (isdirsep (sep)
           {
             /* This converts // to /, but since both give EEXIST, we're okay. */
             char *buf;
             char *p = stpcpy (buf = tp.c_get (), dir) - 1;
             dir = buf;
             while (p > dir && isdirsep (*p))
               *p-- = '\0';
             /* Reattach dirsep in case of "x:". */
             if (p == dir + 1 && *p == ':' && isalpha (dir[0]))
               p[1] = sep;
           }
