It was a fix for this bug:

  http://www.gccxml.org/Bug/view.php?id=7148

For this code:

  struct A { template <class T> A(T&); };

gccxml was dumping no constructors at all which made the class look
default-constructible.  We still don't dump the template, but now
someone reading the output can assume from the lack of a default
constructor that there is no such constructor available.

After this fix, all constructors and destructors that exist for a class
are dumped whether the user declared them or not.  Those that were
implicitly declared by the compiler are marked as "artificial".
