[PATCH v3] Remove defines to builtins in string2.h

[Florian Weimer]

* Wilco Dijkstra:

> -#ifndef _HAVE_STRING_ARCH_strchr
> -# define strchr(s, c) __builtin_strchr (s, c)
> -#endif

Current master has this:

#ifndef _HAVE_STRING_ARCH_strchr
extern void *__rawmemchr (const void *__s, int __c);
#  define strchr(s, c) \
  (__extension__ (__builtin_constant_p (c) && !__builtin_constant_p (s)	      \
		  && (c) == '\0'					      \
		  ? (char *) __rawmemchr (s, c)				      \
		  : __builtin_strchr (s, c)))
#endif

So I'm afraid the patch doesn't apply.
