Package: libc
Version: 4.6.27-5

If you use 'gcc -O -traditional' and include stdlib.h it barfs about
multiple definition of a few things...

tim@morgoth:~/> cat test.c
#include <stdio.h>
#include <stdlib.h>

int main()
{
        printf("Hello world\n");
}
tim@morgoth:~/> gcc -O -traditional -o test test.c
In file included from test.c:2:
/usr/include/stdlib.h:154: conflicting types for `initstate'
/usr/include/stdlib.h:143: previous declaration of `initstate'
/usr/include/stdlib.h:156: conflicting types for `setstate'
/usr/include/stdlib.h:144: previous declaration of `setstate'
/usr/include/stdlib.h:196: conflicting types for `cfree'
/usr/include/stdlib.h:191: previous declaration of `cfree'
tim@morgoth:~/>


An example from the stdlib.h follows:

#ifdef  __USE_MISC
/* Free a block.  An alias for `free'.  (Sun Unices).  */
extern void cfree __P((void * __ptr));

 #ifdef  __OPTIMIZE__
#if defined(__cplusplus) || __GNUC__ >= 2
extern __inline void cfree (__ptr_t __ptr)
        { free (__ptr); }
#else
#define cfree(ptr)      free(ptr)
#endif
#endif  /* Optimizing.  */
#endif  /* Use misc.  */


It would seem that there needs to be some more checking that it
doesn't get __USE_MISC and __OPTIMIZE__ defined at the same time (or
indeed that it does the right things when it gets it!)
