For info: aligned_alloc undefined

[tomdeakin]

On systems with GLIBC < 2.17 C11 is not available, and so aligned_alloc is not defined. It can be defined using the POSIX equivalent by adding the following to the code:

void* aligned_alloc(size_t alignment, size_t size)
{
    void* mem;
    posix_memalign(&mem, alignment, size);
    return mem;
}

Pre 2.17 GLIBC versions are no longer supported by the GLIBC developers. However RHEL 6 currently uses an old version with a long EOL on this distribution. Keeping this issue alive for information only.
