when is a GDC/D2/Phobos bug a GDC bug?

FWIW, SVN Phobos passes 64-bit semantic analysis even with unittests
instantitating templates on DMD.  DMD is mostly 64-bit capable, but a lot of
nitty-gritty issues remain before it can be used for anything more than semantic
analysis.  Phobos 2.050 hadn't been fully fixed for 64 support.  Iaian has
apparently been patching it to get it to compile, but a more thorough job was done
on the main SVN trunk recently.
