On windows, an #endif in a wrong place was causing an early
return from mysql_load and thus the LOAD DATA LOCAL was not
executed. This problem was fixed by moving the #endif to the
right place.

The following code was missing
    
  if ((stat_info.st_mode & S_IFIFO) == S_IFIFO)
    is_fifo = 1;

which is required to properly configure and read from the
IO_CACHE when a named pipe is used. So it was re-introduced
before the #endif.
