One counterexample is the vendor-supplied compiler on the main server of our
department, which is running Solaris 5.10 (circa 2005). This compiler is Sun C
5.9 (circa 2009). Although more recent versions of this compiler do support
anonymous structs and unions, bug reports are still being filed about the
feature, e.g., https://community.oracle.com/thread/4106986 dated December 2017.
So I would say it's still a bit dicey in more-recent versions.
If it were really important to require this C11 feature I suppose we could forge
ahead and do it and tell laggards to upgrade their compilers or use GCC. But my
impression is that the feature is mostly just a nicety, at least for Emacs.
