You are missing the line #include <stdio.h> -- this header file is
required when using the standard IO functions and it defines symbols
like stdout.  Technically, it's even required when you use printf, but
your program happens to compile because GCC happens to do the right
thing without the printf declaration.

This is not an accident: GCC was designed in part to be forgiving to C
programmers who don't do things they technically should do.  I have
used an ANSI compiler which did NOT forgive using printf without
including stdio.h!
