It doesn't seem to work. #include <libc/features.h> added to stdio.h.
----- include/libc/features.h starts. -----
/* Copyright (C) 2000 DJ Delorie, see COPYING.DJ for details */
#ifndef __dj_include_libc_features_h__
#define __dj_include_libc_features_h__

#ifdef __cplusplus
extern "C" {
#endif

#if __STDC_VERSION__ >= 199901
#define STDC_VERSION_IS_BIGGER_THAN_199901 1
#elif __GNUC__ >= 2 && __GNUC_MINOR__ >= 91
#define restrict __restrict__
#else
#define restrict
#endif


#ifdef __cplusplus
}
#endif

#endif /* __dj_include_libc_features_h__ */
----- include/libc/features.h ends. -----
----- Output from making in src/libc/ansi/assert/assert.c with -E starts. -----
gcc ... -c assert.c
# 1 "assert.c"

# 1 "../../../../include/assert.h" 1


















void    __dj_assert(const char *,const char *,int)
__attribute__((__noreturn__))
;








# 2 "assert.c" 2

# 1 "../../../../include/libc/features.h" 1

etc...
----- Output from making in src/libc/ansi/assert/assert.c with -E ends. -----

So for some reason it skips the defines although "gcc --version"
reports "2.952" and compiling with "-v" reports "-D__GNUC__=2
-DGNUC_MINOR__=95".

Am I missing something?


Right,
