redefining stdout/stderr

[ashitpro]

when I declare

#ifndef stdout
#define stdout 0
#endif

#ifndef FILE
#define FILE void
#endif

it gives me warning as "redefined in stdlib.h".
How can I prevent #include<stdio. h> or #include<stdlib .h>
for particular translation unit?

this is how stdout is define.

#ifndef _STDSTREAM_DEFINED
#define stdin  (&__iob_func()[0])
#define stdout (&__iob_func()[1])
#define stderr (&__iob_func()[2])
#define _STDSTREAM_DEFINED
#endif

if you set stdout to zeor your application will fail if you use printf function or scanf function or any function that print on standard output. It does not warn me? why?

I think I solved my problem by re-arranging the headers. By the way, my code can not be dependent on c-runtime. someone else will plugin their platform specific code. The reason, I was suppressing those "#defines" is that particular code is auto-generated by lex.
