Workaround bug in GCC trunk.
Workaround bug in GCC trunk.

For some reason GCC ToT is failing to deduce the auto type for
a static data member from its initializer in some cases.

Though I'm sure the bug will be short lived, there is a trivial workaround for it.
So we might as well get the bot passing again.
