Without special requirement or using obsolescent compiler, the compiler usually chooses the #else so that sa_handler is one of members.
But irony doesn't show any candidates for sa_handler, my irony gives
There are duplicated items for the same candidate. That's because I'm using both irony and rtags. Both of them don't show sa_handler. But since they use clang as backend. I suspect it is a problem of clang, isn't it? There is another possible reason that I can come up with, that is there may be an option about compiler definition which should be given to irony but omitted.
