Has anyone ported the AT&T Typesetter-independent Troff package (also
known as Device Independent Troff or DWB) to a Sun-4?  I have both
DWB-1 and DWB-2 (properly licensed!) but compiling them on the Sun-4
results in an immediate segmentation violation.

When Kernighan rewrote Troff into Typesetter-independent Troff, he
utilized a pair of routines fdprintf and sprintf as scaled down
versions of the library routines.  Unfortunately, these two use
variable numbers of arguments accessed through a stack pointer which 
is a no-no on the SPARC.

So, before I go in with my machete and hack and slash this stuff into
shape with varargs(3) (or switch back to the library routines), has
someone already done the work?  I haven't even got to any possible alignment
problems yet!
