That is not entirely true.  IEEE Std.1003.1-2001 describes a set of
base interfaces and several sets of layered options which complement
the base interfaces.  SUSv3 uses the same document, but some of the
interfaces which are optional in 1003.1-2001 are mandatory in SUSv3.
Most significantly, this includes the XSI option, which standardizes
old System V (and X/Open) mistakes.
