patch to compile on gcc4.1 (anonymous namespace)

[William C. <wc...@re...>]

GCC 4.1 is pickier about the anonmous namespaces, code can't have a 
class method in a namespace if the class declaration doesn't have it in 
the same namespace. One of the member functions was included in an 
anonymous namespace. GCC 4.1 complained about this. The attached patch 
fixes the problem. Does this look reasonable?
