The "w" modifier should have been supported since clang 3.4, > and is certainly supported in clang 3.5. Uh, you are right. I have no idea why my earlier tests failed... Sorry. So I would mostly like to see this 'w' modifier documented in the gcc doc, and a warning that includes a hint about 'w'. (For clang I only have 3.5 and svn215195 of 3.6 and the note part is not present yet) Thanks.
