I've send a simple test to test bot. It doesn't crash there, it also 
shows when read_s should succeed and fails with your implementation.

Something like this should work (it's a copy of implementation that is 
in msvcrt):
int CDECL _fclose_nolock(FILE *file)
{
     int r, flag;

     flag = file->_flag;
     free(file->_tmpfname);
     file->_tmpfname = NULL;
     /* flush stdio buffers */
     if(file->_flag & _IOWRT)
         fflush(file);
     if(file->_flag & _IOMYBUF)
         free(file->_base);

     r=_close(file->_file);

     file->_flag = 0;

     return ((r == -1) || (flag & _IOERR) ? EOF : 0);
}

It's also not needed to check for functions existence in tests.
