The parser allows:

extern(C++)
extern(C++, Identifier.List)
extern(C++, struct)
extern(C++, class)
extern(C++, Expression[, Expression...])

Expression must be a compile-time evaluate-able string, otherwise
compile error in semantic.

Parens are just a hack to make it not caught by the Identifier case,
it will be properly parsed an Expression.

Do you have reason to believe it wouldn't use the release DMD build to
build the docs for each release?
