Well, maybe I'm missing something but I can't any see code in GCC for
generating prologues, epilogues and unwind tables in the format required
by the Windows x64 ABI.

How exactly are you testing this?  Without SEH support Windows wouldn't
ordinarily ever need to unwind through GCC compiled code.  I assumed
that's why it was never implemented.
