Which package may be missing ? "dpkg -l | grep dev" gives :

ii  dpkg-dev       1.6.15         Package building tools for Debian

The faulty operation is FPOS_EQ defined as

#if defined (_POSIX_)
#  define FPOS_EQ(p1, p2) ((p1) == (p2))
#else /* _POSIX_ */
#  if     !__STDC__ && _INTEGRAL_MAX_BITS >= 64
#    define FPOS_EQ(p1, p2) ((p1) == (p2))
#  else
#    define FPOS_EQ(p1, p2) \
            ((p1).lopart == (p2).lopart \
             && (p1).hipart == (p2).hipart)
#  endif
#endif  /* _POSIX_ */
#else
#define FPOS_EQ(p1, p2) ((p1) == (p2))
#endif

and only used in this fragment of main.c

              if (FPOS_EQ(pos1, pos2))    /* no RTF output */
              {
