Nope thats me not proofreading my posts properly, sorry.

Hmm thats, odd unless there are other fields with initialisers 
that are forcing its emission.

Try not using the .di files at all. I've never had any use for

definitions of the functions and types declared by the headers. 
this can be done with a .d file.
