From 1575fd4adcb97a078bbce261ff2c20c82363e89a Mon Sep 17 00:00:00 2001
From: Paul Eggert <eggert@cs.ucla.edu>

Subject: [PATCH] (gl_MACROS): Require AC_FUNC_LSTAT. Don't check for memcpy,
 strchr, strerror, strrchr, float.h. Use AC_REQUIRE on AM_LANGINFO_CODESET and
 gl_GLIBC21 rather than invoking them directly. (gl_CHECK_ALL_HEADERS): Don't
 check for errno.h, float.h, limits.h, stddef.h, since we assume C89 now.
