But C++98 doesn't require support for __asm.

# ifdef __CORRECT_ISO_CPP_STRING_H_PROTO
extern "C++" void *rawmemchr (void *__s, int __c)
     __THROW __asm ("rawmemchr") __attribute_pure__ __nonnull ((1));
extern "C++" const void *rawmemchr (const void *__s, int __c)
     __THROW __asm ("rawmemchr") __attribute_pure__ __nonnull ((1));
# else
