I take that back, there is something wrong:

#ifndef __has_feature
#define __has_feature(x) (0)
#endif

#if __has_attribute(alloc_size)
#error Has attribute
#endif

$ cc -E attr-text.c
# 1 "attr-text.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "attr-text.c"
attr-text.c:5:20: error: missing binary operator before token "("
