I made the patch below and got further:

g++ -I. -I/xxx/gnu/groff-1.17.3/src/preproc/pic 
-I/xxx/gnu/groff-1.17.3/objdir/src/include -I/xxx/gnu/groff-1.17.3/src/include 
-DHAVE_CONFIG_H -O2  -c /xxx/gnu/groff-1.17.3/src/preproc/pic/pic.cc
/xxx/gnu/groff-1.17.3/src/preproc/pic/pic.y: In function `char*
   do_sprintf(const char*, const double*, int)':
/xxx/gnu/groff-1.17.3/src/preproc/pic/pic.y:1780: `snprintf' undeclared (first 
use this function)

Although the system libc has snprintf and vsnprintf, there is no declaration
in the hpux 10.20 header files or any documentation on these functions.  I
seem to recall in helping to port autogen to hpux that there were reasons
why the system versions of snprintf and vsnprintf shouldn't be used.
