I think you are right.  However, they often use "POSIX-compliant"
loosely. Something that would be better described as "POSIX-like" or
"almost POSIX-compliant for our practical needs", or even

"Unix-like-like-the-one-we-used-to-build-and-run-our-code-successfully".

Absolute and strict compliance to a given standard, with almost
mathematical certainty, is something rather theoretical.  I'm not an
expert, but I think that, even without 'POSIXLY_CORRECT' set, GNU
is a quite good "POSIX-compliant" OS in the vulgar sense, given that it
satisfies the majority of programs intended to run under
"POSIX-compliant" operating systems.  And, IMHO, that's what they
usually mean.
