<pre>__has_cpp_attribute is defined for C programs, but cannot parse scoped
attributes. It seems like this predefined macro should not be defined for
non-C++ targets, or it should support scoped attributes (and resolve to false
always) when in C mode. My preference is for the builtin to not be defined when
compiling for C as that would match the documented portability suggestions.</pre>
