Ok, thanks.  So I'll implement my manual hack in fixincludes and submit
that patch once I'm ready.

I'll probably try to get a fix into OpenSolaris for CR 6549313

        http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6549313

so the fix will become unnecessary in the future.

What I don't fully understand yet is whether imaginary support in GCC
isn't/won't be there simply because it's been removed from C99 or nobody
thinks the work to implement it is worthwile.
