           Summary: [c++0x] outer inlined namespace vs. inner nested
                    namespace
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED

test for nested inline namespace

Interesting g++ behavior I ran into while revamping "versioning with inline
namespaces", which I believe to be a bug.

Compiling the attached as so:

$bin/H-x86_64-gcc-trunk.20110124/bin/g++ -c -g -O2 -std=gnu++0x
inline_ns_trouble.cc

ok, great.

adding an inlined namespace however gives error:
%$bin/H-x86_64-gcc-trunk.20110124/bin/g++ -DBUG -c -g -O2 -std=gnu++0x
inline_ns_trouble.cc
inline_ns_trouble.cc:68:14: error: ‘treat_as_floating_point’ is not a template
inline_ns_trouble.cc:70:7: error: explicit specialization of non-template
‘std::chrono::treat_as_floating_point’

A nested namespace of an inline namespace does not map onto a nested namespace
of the enclosing namespace; you need to have one chrono namespace and two
inline namespaces, rather than one inline namespace and two chrono namespaces.
