True on both counts.

On a related note, we already have __rw_compile_assert [see rw/_defs.h],
but it doesn't work at global or class scope.

I provided an __rw_static_assert for use with type_traits in my original
patch, but it didn't work outside of a template. I've got an updated
version that will work in all cases. I'm thinking that I should replace
the existing __rw_compile_assert with __rw_static_assert, and then
define a macro _RWSTD_STATIC_ASSERT(Cond,Mesg) that uses static_assert
if it exists, or falls back to ours as needed.
