This patch returns NULL if default_argument is error_mark_node. 
So if parsing the default argument fails, we pretend the parameter itself
didn't exist?  Why does that work better than just setting default_argument
to NULL_TREE?

I still got 

/tmp/x.ii:19: internal compiler error: canonical types differ for
identical types void (A::)(void*) and void (A::)(void*)

Yes, I expected that it wouldn't work better, I was curious why it makes a difference. It seems that the problem is coming in when we build the method type.
