Thomas,
Oh man!! That's a subtle piece of info, any reason the END can't be left in there as a default somehow or at least ignored inside of the STYLE block, I can see this coming back to bite folks over time with the two different formats for SYMBOL/(and sometime END) combos.

third time's a charm :)
LAYER
NAME business_rd1
CONNECTIONTYPE POSTGIS
CONNECTION "host=localhost dbname=Business user=postgres password=xxxx port=5432"
DATA "geom From business_rd1 as rd1 using unique id using srid=4326"
PROCESSING "CLOSE_CONNECTION=DEFER"
#MINSCALE 10000000
STATUS ON
TYPE POINT
CLASS
STYLE
SYMBOL 'circle'
SIZE 2
COLOR 255 0 0
END #Style
END # Class
END # Layer
symbol takes an END when you're defining a symbol , not when referencing it in a style.
