Hi,
two years ago, I've added posix syntax and so to my locally ps(1). for instance,
I'm
currently adding the notion of dynamic personalities (the term comes from linux)
instead of static #define such as... say :
$ ps -X help
any bsd bsd43reno bsd44 default extended freebsd hpux irix netbsd none openbsd
pedantic posix relaxed solaris sunos susv3 tru64
personalities enable options such as :
bsd ps :
-g and -n from sunos, -s from tru64 and some other options.
posix ps : see susv3 man (see
http://www.opengroup.org/onlinepubs/007904975/toc.htm)
-j from all except posix
-c, -y and -P from solaris
-C cmdlist (ala pgrep :) and -x from hpux
-M from irix
and some others
they also enable many keywords such as :
RUSAGE and co from tru64, class and psr from solaris, and many others
(mostly aliases)
when finished, I'll probably submit these changes as a port in the meantime
since I suppose -arch will reject these important changes to a native command.
the most important and not done part is... the manual page. any volonteers ?
here are some sample outputs :

PS : note the S (O means on cpu), RSS.VSZ (tru64 format) and TIME (posix format)
columns...
all internals are dynamically generated, such as format strings :
for native freebsd :
label:Z user:!nju uid:!d!vnl pid:djl1uv ppid:jl pgid:j jobc:j cpu:l pri:l nice:l
%cpu:u %mem:u vsz:lu rss:lu mwchan:!nl tt:d2u state:djl2uv start:u tt:jl
time:djl2uv sl:v re:v pagein:v vsz:v rss:v lim:v tsiz:v %cpu:v %mem:v
command:djl2uv
for native susv3 :
f:!ylx s:lx user:fx uid:l pid:dflx ppid:flx c:!cflx pri:!clx intpri:c nice:!clx
addr:!ylx vsz:lx wchan:lx tty:dl stime:fx tty:fx time:!Ldflx comm:dl args:fx
for extended susv3 :

c:!cflx class:c pri:!clx intpri:c nice:!clx psr:P addr:!ylx rss:y vsz:lx=SZ
wchan:lx tty:dlj s:2 stime:fx tty:fx2 time:!Ldflxj2 comm:dlj2 args:fx
PS : 1 and 2 stand for -O, x stands for -fl, !x say not -x
