I am sorry to say that I don't understand the definition of struct C.
Would you please write an example that compiles?

Anyway, I plan to divide the different cases into several patches, so
each case can be reviewed and tested independently. Also, I will send
each patch and testcases the list, so I am looking forward to reading
your review. It would be quite an achievement for me to see the option
merged into GCC mainline, so it is my intention to follow developers'
comments, and not to push or force any personal agenda.

Cheers,
           Manu.
