r.tiff

Hi,
I tried to compile r.tiff on an HPseries 700, but I miss some .h files:

=========================================
  SRC = /users/andreag/Grass/src
  CMD = /users/andreag/Grass/src/CMD
  HEADER = head
  ARCH =
  GISBASE = /users/andreag/Grass
  VERSION = 4.1 Spring 1993 Update package 3
#################################################################
/users/andreag/Grass/src/raster/r.tiff/tools
  make -f OBJ/make.rules

  cc -o tiffgt -g -I../libtiff cg8gt.c ../libtiff/LIB/libtiff.a \
      -lsuntool -lsunwindow -lpixrect
*** Error code 1

For sure I have no suntool and sunwindow directories (I tried a 'find'
on the missing .h ).
Does this mean that I cannot compile r.tiff on my machine ?
