Ehh..

The compiler is called "gcc", and is invoced as such.

And you apparently entirely dismissed the fact that the Linux behaviour is
based on _documented_ behaviour. And you still want to call it a "bug".

The kernel may be one program, but point me to a _single_ program that
uses trigraphs. Show me _one_ serious program that wants to use them.

The fact is, nobody uses trigraphs. NOBODY. They were a bad idea.

But hey, as good as you are at ignoring documentation, I'm sure you'll
have no trouble at all ignoring reality too.
