[Olena-patches] 591: Work around a bug in g++ 4.1 and 4.2 in tests/vtypes-and-exact.cc.

https://svn.lrde.epita.fr/svn/oln/trunk/static Index: ChangeLog from Roland Levillain &lt;roland(a)lrde.epita.fr&gt; Work around a bug in g++ 4.1 and 4.2 in tests/vtypes-and-exact.cc. * tests/vtypes-and-exact.cc (my_direct_type_of), (my_direct_type_of_): New macros. (my::A::foo_type, my::A::bar_type, my::A::baz_type) (my::B::foo_type, my::B::bar_type, my::B::baz_type) (my::B::quux_type, my::B::yin_type) (my::C::foo_type, my::C::quux_type, my::C::zorg_type): Rename typedefs as... (my::A::foo_t, my::A::bar_t, my::A::baz_t) (my::B::foo_t, my::B::bar_t, my::B::baz_t) (my::B::quux_t, my::B::yin_t) (my::C::foo_t, my::C::quux_t, my::C::zorg_t): ...this. Use my_direct_type_of and my_direct_type_of_ (on the exact type) instead of my_type_of and my_type_of_ (on the ``self'', current type) to work around a bug in g++ 4.1 and 4.2. (main): Adjust. * tests/Makefile.am (AM_CXXFLAGS): Rename as... (CXXFLAGS): ...this.
