I haven't seen anybody else replying so I do it now.  But these are no
final answers since I have nothing to say in gcc.

It hasn't been done and, yes, I've written the code to explicitly
allow other formats to be written.

This I don't understand.  Why should you have problems handling more
than one -d option?  At the end of every compiler pass the output file
should be closed.  Which means with the beginning of the new pass the
plate is cleared and you can start again.
