Yes, I got the same error when I tried to compile it.  I believe that changing
the #define so that HUGE is 1.7e+18 will allow it to compile.  The program
seems to work correctly with this change, but I haven't tested it extensively.

Does anyone know if this is in fact a problem with the compiler?  There is
a #define in the include file math.h for something called HUGE_VAL, or 
something like that;  As I remember,  it is something like 1.79e+308.  
Ray would not compile using this either (resulted in same error).  
Does anyone know if this is a real problem or just something weird about
the DBW source?
