Mapserver 5.0.0 and ANGLE for label class

[Luca Manganelli]

Hi, I have a field with angles in degrees. The attached mapfile
doesn't rotate the label. I used this in Mapserver 4.x without
problems:

LAYER
   [...]
   TYPE POINT
   TEMPLATE void
   CLASS
    [...]
   END
   LABEL
     TYPE TRUETYPE
     ANTIALIAS TRUE
     FONT arial
     SIZE 20
     MINSIZE 4
     MAXSIZE 30
     ANGLE [field]
     FORCE true
     OFFSET 0 0
     POSITION cc
     PARTIALS TRUE
     COLOR 255 0 0
   END
END

How can I fix this?
