SPUG: Any grep's lack \b functionality?

Boeing's install of AIX 4.3 has grep, egrep, fgrep, and ogrep.  ogrep has no man page, but the usage is similar to other greps.  fgrep has a "-w" word search flag, but there appears to be no true word boundary functionality.  So on this AIX, there is no \b available.

Good luck with the book.

   [snip]

So one question I'd like help answering is:

1) Is any fairly contemporary version of UNIX missing a grep,
   egrep, or sed that supports a word boundary metacharacter?
   (\b, \<, whatever)

But the more general question that really interests me is:

2) Does anybody know where I can find a detailed list of the
   capabilities of each of the UNIX utilities (grep, sed, sort,
   tail, etc.) as they're provided by different Unices?

TIA,

-Tim
