Title: Disabled macro expansion

These macros defined in Emscripten's stdio.h cause clang warnings (warning: disabled expansion of recursive macro [-Wdisabled-macro-expansion]) every time stdin, stdout, or stderr is referenced. Whatever the original change was intended to do can likely be achieved some other way that doesn't cause warnings.
