Because ANSI is defining a language, not an operating system.

A Cyber 205 doesn't need sbrk -- refer to a word and it exists, regardless
of its address. And it can't use shmop -- only the site defined shared library
pages can be shared (in read/execute mode).  (Not that 205 is all that great
or VectorC that well known, but it does provide a concrete example.)
