ChangeLog:

2014-03-17  Will Newton  <will.newton@linaro.org>

	* crypt/md5.c: Check whether _STRING_ARCH_unaligned
	is defined with #ifdef rather than #if.
	* crypt/sha256.c: Likewise.
	* crypt/sha512.c: Likewise.
	* include/arpa/nameser.h: Likewise.
	* stdlib/getenv.c: Likewise.
	* string/bits/string2.h: Likewise.
