// Note: this mimics how interceptor functions are defined in the compiler-rt
// libraries. Despite a declaration in the system header having an exception
// specification, redeclaring it in the user code does not produce the "missing
// exception specification" error. Consequently, there should be no warnings
// about type mismatches for the alias and its aliasee.
