s/SUSv3/POSIX:2004/ and s/SUSv4/POSIX:2008/?

SUS includes SystemV-specific interfaces on top of POSIX that are not
generally available on BSDs (including probably OSX).  Those should
not become mandatory.  And I agree that it is too early to start
relying on POSIX:2008; I don't think anybody fully implements it,
although Solaris and Linux are probably very close.
