[Bug c++/21369] New: Template function definition rejected if function return type begins with 'struct'

["pkoning at equallogic dot com" <gcc-bugzilla at gcc dot gnu dot org>]

This test program:

struct bar;

template <class T> struct bar *foo (T *p)
{
    return p->t;
}

produces an error in 4.0.0:

test.cc:3: error: 'bar' is not a template type

Without the keyword "struct" it compiles fine.  Earlier versions
(3.3.2, and I'm pretty sure 3.4.1 as well) don't complain.

I've seen this on a native Linux build, and also a crosscompiler targeted at
netbsd-mips and hosted on i386-mips.
