FILE pointer incompatible with stdin

I have the following code

struct FILE *in, *out;

if (argc == 1) {
    /*  No files were supplied so assume parsing from the stdin and printing to the stdout */
    in = stdin;
    out = stdout;
}

However when compiling with gcc using flags -ansi -Wall -Wextra -Werror the following error occurs: assignment from incompatible pointer type.

I looked up on the GNU C Library Reference Manual for the type of stdin and on page 227 (251 on Adobe Reader) the type in indeed FILE * so I don't know what is wrong.

Drop the struct and include stdio.h to get the typedef.
