These data areas are set up by Foundation to link in as real classes post facto. 15*1031c584SApple OSS Distributions * 16*1031c584SApple OSS Distributions * We keep these in a separate file so that we can include the runtime code in test subprojects but not include the data so that compiled code that sees the data in libSystem doesn't get confused by a second copy.
