Hi there,

if I compile the following simple program

--------
#include <stdio.h>

int main ()
{
    printf("Hello world !\n");
    return 0;
}
--------
with "gcc -Wall -target sun4 -o w w.c" using gcc-2.3.3 on a Sun
SPARCstation 1+ running SunOS 4.1.1, I get
--------
w.c: In function `main':
w.c:5: warning: implicit declaration of function `printf'
--------

I thought by writing "#include <stdio.h>" I have already taken care of
the proper declaration of printf() !?
Any hints whether I have missed something or whether gcc is incorrect
here are welcome. Should I care about the warning at all ?

Thanx in advance,
                 MARKUS
