A patch and test case which sets in _flsbuf the file->_cnt to 0

With this change the make command runs.
There is still a problem with the child processes.
I'm not sure when exactly to set flag->_cnt to 0.

(Also is in MSVCRT_fwrite
  memcpy(file->_ptr, ptr, pcnt);
is there check needed if file->_ptr is a valid pointer?)
