I would propose to remove support for a couple of extremely old platforms
as well:

- Cray/UNICOS 9. This was apparently released in 1996 [1] and still a 
portability
  target in 2005 [2].

- Ultrix. Last release was in 1995 [3]. A portability target up to 2005 [4].

- SVR3 (released in 1987) and SVR2 (released in 1984) [5].

- DolphinOS (a particular SVR3) [6].

- DECstation (defined decstation). Last released in 1994. [7]

- Dynix/ptx (defined _SEQUENT_, defined sequent). Released in 1992. [8]

- Sony NEWS (defined sony_news). Last released in 1993. [9]

- ardent (last released in 1988). [10]

- tek4300 (must have existed in 1988). [11]

- alliant (before 1992). [12]

- ConvexOS (defined convex). Last release before 1995. [13] GCC support removed
  in GCC 3.3 [14], i.e. in 2003.

- HP-UX on m68k (defined hp9000s300). Last released in 1991. [15]

In all modules (fsusage, mountlist, getloadavg in particular).
