+In GCC 4.6 the compiler no longer allows objects of const-qualified type to
+be default initialized unless the type has a user-declared default
+constructor.
+
+Patch from Gentoo bugzilla: http://bugs.gentoo.org/show_bug.cgi?id=358021
+
+Gentoo Bugzilla description follows:
+"If a class or struct has no user-defined default constructor, C++ doesn't
+allow you to default construct a const instance of it.
