Cannot compile groff-1.19 on Tru64Unix 5.1A

[Martin MOKREJŠ]

Hi,
  I found a bug in cxx compiler on Tru64UNix. Maybe you want to consider
some recommendation from the cxx developers. In future there might be a fix
in compiler. I have currently latest version:

$ cxx -V
Compaq C++ V6.5-033 for Compaq Tru64 UNIX V5.1A (Rev. 1885)
Compiler Driver V6.5-033 (cxx) cxx Driver
$

Hope this helps
