Problems building ddd on HPUX 11.31 IA64

While building ddd version 3.3.11 on HPUX 11.31 with aCC  Version A.06.15, I
ran into the following problem.
"ArcGraphE.C", line 50: error #2308: more than one instance of overloaded
functi
on "hypot" matches the argument list:
            function "hypot(double, double) C"
            function "hypot(float, float)"
            function "hypot(long double, long double)"
            argument types are: (const BoxCoordinate, const BoxCoordinate)
      return hypot(p[X], p[Y]);

The function hypot is called in 3 files and I patched the three files as
provided under.  Hope this is inline with what is intended.  I did not make
the fix hpux specific as this should be compileable on all c++/g++
implementations

I also checked the latest code in CVS and this problem has not yet been
fixed

Thanks
