There's portability between systems, which as you note, has ever-diminishing returns.

Then there's portability between compilers, which, as the article notes, glibc is also completely hostile to (except for anointed compilers) for no good reason whatsoever.

This is neither true nor claimed by the article.

The article specifically states "If you aren't gcc, clang, or tcc, tough luck."

It doesn't work. For no good reason. Because there are a few anointed compilers.

That it wasn't on purpose doesn't make it not hostile.
