We don't seem to have any mentions of POSIX or SuS in docs, in the 
installation sections. There are a few mentions of POSIX-1.2008 and 
POSIX-1.2001 it in the commit log, though, where we require features 
specified by those. Can we rely on everything from POSIX-1-2008 
nowadays, or is it more on a case-by-case basis, depending on which 
parts of POSIX are supported by various platforms?
