I got some warnings while compiling part of boost with clang TOT.
In particular, it warned about "extra ; in class definitions"
> In file included from ../../../libs/test/src/unit_test_monitor.cpp:16:
> In file included from ../../../boost/test/impl/unit_test_monitor.ipp:22:
> In file included from ../../../boost/test/test_tools.hpp:19:
> ../../../boost/test/predicate_result.hpp:44:37: warning: extra ';' inside a struct [-pedantic]
> struct dummy { void nonnull() {}; };
So (after some prodding), I looked in the standard and found section 9.2 (class members), where it
appears to show that the semicolon after the member function definition is optional.
Then I went to http://clang.llvm.org/docs/UsersManual.html , where it says that
> -pedantic: Warn on language extensions.
It seems to me that the extra semicolon is not a language extension.
What is the rationale behind having it warn, then?
