The "nroff"/"troff" available on the Suns (not all upper-case) *is* an
AT&T nroff/troff.  It's just an older one, of about V7 vintage....

>so the easiest solution is to get an AT&T version of nroff/troff.

Or, more correctly, "get a newer AT&T version of nroff/troff".  The
easiest way to do that is probably to pick up one of the binary versions
of Documenter's Workbench 2.0 (which, I think, contains the newest AT&T
versions of nroff/troff).  There are, I think, at least three of them
out there, namely Elan Computer Group's (EROFF), SoftQuad's (whose name
I don't remember), and some third company's ("Profficient"?).  I suspect
that some subset of the vendors of those products have already been
heard from, or are reading this group and may be heard from.... 

(Another fix is to whack on the macros, as Jaap Akkerhuis suggested.)
