Good question. My guess is that it's because lookup_symbol_aux()
calls current_language->la_lookup_symbol_nonlocal() before it calls
lookup_symbol_aux_psymtabs(). If I force la_lookup_symbol_nonlocal()
to return NULL, then lookup_symbol_aux_psymtabs() finds the typedef,
and `ptype T5<int>' works more or less correctly.
One solution might be that when gdb finds that a symbol has a class
definition, it makes sure that it does not have a pseudo-namespace
definition.

If it helps, that's more or less what my libiberty C++ demangler does.
It first translate the name into a simple tree structure, and then
walks the tree translating it into a string. I could expose the tree,
although it would have to be documented a bit better.
