"A lot of things"? Let's keep a sense of proportion: it broke exactly one thing and that's gnustep. This isn't the first time that Apple's language extension broke system headers either, see __block and glibc. Objective C has no more ownership of "__weak" than the OS has and the common style of header keywords is actually a much stronger reason *against* the pseudo-keyword use in Objective C. Joerg
