The PDP-11 myth is getting a bit tired by now ;)

If C would be so hardwired to the PDP-11 architecture it would have died with it. In reality C works just fine on all sorts of hardware (like GPUs) with only minor extensions.

Just like plenty of other programming languages.

I am also tired that language extensions in C to work around ISO defencies is considered an advantage when argued by C folks, while at the same time it is considered a language design fault when the same crowd points to other programming languages.
