[Bug c++/29352] New: `bound_template_template_parm' not supported by dump_decl

["olsner at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Basically, g++ seems to have forgotten how to print some part of the error
message.

The errant code:
template <typename T>
struct s1
{
        typedef T* ptr_type;
};

template <typename T, template <typename> class U = s1>
struct s2
{
        typedef U<T> UT;

        operator /*typename*/ UT::ptr_type ()
        {       return 0; }
};

And the output:
test.cpp:12: error: `#`bound_template_template_parm' not supported by
dump_decl#<declaration error>::ptr_type' is not a type

Uncommenting the typename keyword fixes the error in the code. No extra
compiler options were used.

The bug is not present in 4.1 (4.1.2 20060901 (prerelease) (Debian 4.1.1-13)),
where gcc instead outputs "error: expected type-specifier".
