Although the syntax might look ugly (I don't really like the whole
thing), removing support for __complex__ from cc1plus is out of
question.  There are far many ways in which cc1plus  has to grok those
documented harmless GNU extensions. 

If you're looking for removal of documented harmful extensions, start
with statement-expressions :-)
