boost::format::operator% does not work with anonymous types inside a namespace

[Geoff Barrett <gbarrett@…>]

Using g++ version 3.3.3. Actual sources are from 1.33.1 but these don't seem to be different from what is currently in the repository. I get the following error message. If I remove the template specification from the calls in the body of several functions, the errors go away. In the attached file, the function foo2 suffers the same problem as operator% but foo1 does not.

With g++ 4.2.1, this change does not work either.

.../boost/format/format_class.hpp: In

member function `boost::basic_format<Ch, Tr, Alloc>& boost::basic_format<Ch, Tr, Alloc>::operator%(const T&) [with T = bcu::<anonymous enum>, Ch = char, Tr = std::char_traits<char>, Alloc = std::allocator<char>]':
