// TODO(https://fxbug.dev/42105189): These are defined as macros in
// <zircon/compiler.h> and used by some other headers such as in libzx.  This
// conflicts with their use as scoped identifiers in the llvm-libc code reached
// from this header, when this header is included in someplace that also
// includes <zircon/compiler.h> and those headers that rely on its macros.
// <zircon/compiler.h> should not be defining macros in the public namespace
// this way, but until that's fixed work around the issue by hiding the macros
// during the evaluation of the llvm-libc headers.
