Macros for boolean values

Description

In ulinet.h, the following conditional macro definition

   #ifndef true
      #define true 1
      #define false -1
   #endif

is a potential problem because C treats non-zero values as true, so passing the above macro false to a library function with a boolean input parameter will cause unexpected results. The same macro definition appears in service.h (there only for non-Windows platforms). The macro false should probably be defined as 0.

Thanks a lot for this report, this is solved in r621 for ulinet.h and from r618 form service.h.
