This is just my algorithm for converting an internal representation of the type into C type-spec syntax. It was easier to put the parentheses in everywhere than to try and figure out where they can be omitted. But I suppose I can suppress them in the simplest of cases such as the above. (AFAIK this doesn't affect the resulting code in any way. But converting field selections to casts and offsets may be affecting code optimisation so I will try and tidy that up.) -- Bartc
