I successfully compile d.area with the following change in in screenpoly.h
(wrapping the #if !defined code)  

#ifndef __INTTYPES_INCLUDED

#if !defined(uint8_t)
  typedef unsigned char uint8_t;
#endif
#if !defined(uint32_t)
  typedef unsigned long uint32_t;
#endif

#endif

---------------

uint8_t and uint32_t are defined in /usr/include/sys/_inttypes.h where they 
are defined under __INTTYPES_INCLUDED the following way

typedef unsigned char uint8_t; 		/* 8-bit unsigned integer */ 
typedef unsigned int uint32_t;		/* 32-bit unsigned integer */

So as uint32_t should be defined typedef unsigned int uint32_t as suggested.

I do not know by which include file _inttypes.h is pick up.

This solution may work on other systems.

----------------------------

d.area run displaying areas and borders but without area or perimeter
information. 
But the module v.area do that.
