Don't use anonymous types declared in an anonymous union.

Don't use anonymous types declared in an anonymous union.

They are a non-standard extension (probably in C1X, IIRC), but clang is unhappy
with them when -Wnested-anon-types is enabled, which seems to be implied by
-pedantic.

With this change and the previous fix for clang, we are now -Werror clean, even
on clang 3.3.

Note that I've used two redudant "struct"s, keeping the "true C spirit". ;-)
