I have a question. I am running on a Solbourne 500/5E with sunos4.1 and
openwindows 3.0 with gcc-2.1.

Given the following program, foo.c:

#include <stdio.h>

main ()
{
printf("Help\n");
}

and the following compile command:

gcc -L/usr/local/lib/gcc-lib/sun4-os4.1/2.1 -lgcc -Wall -O -ansi foo.c

Why do I get the following warning:

Foo.c: In function `main':
Foo.c:5: warning: implicit declaration of function `printf'


?????????

Any and all help would be greatly appreciated.

Either post a response or email me.

Thanks,
