(svn r4074) -Feature: [Makefile] the makefile can now detect if iconv is present in the system
if detected, WITH_ICONV will be defined in the C code
WITH_ICONV is also added to Makefile.config
OSX do not use this flag setting in Makefile.config, as it is set at compile time based on target OS version
the actual C code is not changed as the current iconv code is hardcoded for OSX and would break if any other OS got iconv
This detection system is by request of Darkvater

/* $Id$ */

#include <stdlib.h>
#include <iconv.h>
#include <stdio.h>

/* this is a pretty simple app, that will return 1 if it manages to compile and execute
 * This means that it can be used by the makefile to detect if iconv is present on the current system
 * no iconv means this file fails and will return nothing */

int main ()
{
	iconv_t cd = iconv_open("","");
	iconv(cd,NULL,NULL,NULL,NULL);
	iconv_close(cd);
	printf("1\n");
	return 0;
