[GRASS5] compiling code

[John Gillette]

I am trying to compile a piece of code outside grass. It comes 
from code with the following includes:


(from v.in.tig.basic)
#include <string.h>
#include <unistd.h>
#include <stdlib.h>
#include "gis.h"
#include "CC.h"
#include "dig_atts.h"
#include "Vect.h"

When I try to compile outside of grass, fseek, fopen 
printf, etc need stdio.h.

gcc -g -Wall -D__USE_FIXED_PROTOTYPES__ -ansi test.c

How is that being included in Grass code?

Also, the coordinate conversion library "CC.h", has
this usage changed now that we are going to use the standard
proj4 library?  Do you call proj4 routines directly?
