  Modified files:
    lib/libc/stdio       fseek.c ftell.c 
  Log:
  Add more EOVERFLOW checks.
  
  When file offset tends to be negative due to internal and ungetc buffers
  additions counted, try to discard some ungetc data first, then return EBADF.
  Later one can happens if lseek(fileno(fd),...) called f.e. POSIX says that
  ungetc beyond beginning of the file results are undefined, so we can just
  discard some of ungetc data in that case.
  
  Don't rely on gcc cast when checking for overflow, use OFF_MAX.
  
  Cosmetique.
