Keywords:	darwin stdout UNIX03	Cc:	fawzi@gmx.ch

Description

This can be seen by the following program that doesn't print anything

import tango.stdc.stdio;
void main(char [][] argv) 
{ 
    fprintf(stdout,"lll\n");
    fflush(stdout);
}

a patch for it is

This is based on the assumption that one has UNIX03 conformance. This seems to be the case in 10.4.11 (and likely in 10.5 that is officially UNIX03 conformant). The following c program can be used to check what is the case (please note that a developer can change the conformance level of his installation using the compat command, but it is unclear if the constant defined would change).

#include <stdio.h>

int main(int argc,char *argv[]){
#ifdef __DARWIN_UNIX03
    printf("new\n");
#else
    printf("old\n");
#endif
}
