I have a grandiose scheme for a C2D project, where rather than storing 
the converted headers (with associated licensing issues), we instead 
store the 'script' (actually more of a hint file) that was used for 
conversion.
It would be fantastic to accumulate a database of C2D files.

Sample C2D script format (excerpt of part of the one that converts the 
Win SDK headers). There are a few other sections, apart from those shown 
here. The C2D program can't do the full Win SDK yet (I'm currently 
working out what to do with bitfields in structs), but it's OK for 
fairly simple headers right now.
