Transparent pixmaps in Mapserver 4.4.1

[Camden Daily]

Thanks Sean.  I'll make a bugzilla report for the MS_ALPHA value.

The image I'm outputting is a 24bit jpeg.  So I need to get the
'transparency alpha' to work properly.

My symbol definition is

  SYMBOL
    NAME 'house'
    TYPE PIXMAP
    IMAGE 'images/house.png'
    TRANSPARENT 0
  END

Do I need the 'transparent 0' line, if the png file itself has a
transparent background?  Commenting it out doesn't resolve my issue,
but I'm not entirely certain what it's for.
