sdl-ios-xcode: src/cpuinfo/SDL

annotate src/cpuinfo/SDL_cpuinfo.c @ 4495:dbbfdb9ea716

Simplified clipboard API for sanity's sake. A complete clipboard implementation would support multiple formats that could be queried at runtime, events for when the clipboard contents changed, support for HTML, images, etc. We're not going that crazy, at least for now. :)
