 Strictly speaking the spec doesn't say that the errno shouldn't be
 touched. Though, usually, when errno is expected to be set, it is
 explicitly mentioned. Moreover, what's the use of returning an error
 code and setting errno at the same time ? As far as I know, glibc
 doesn't set errno, nor DragonFly's libc. On the other hand, sun OS
 5.10 and NetBSD do. Again, this is not a bug, but I think it would be
 nice to have. At the very least it should be documented in
 posix_memalign(3) that the function sets errno.
