One further thought...

As of C11, there is a type max_align_t, defined in <stddef.h>,
whose alignment is the maximum alignment supported by the
implementation.  The grain size for allocation should be a
multiple of

    _Alignof (max_align_t)

so this alignment can be supported.  Also, the amount of space
you use for your "pre-array" metadata should be chosen to be
a multiple of _Alignof (max_align_t), otherwise the array
alignments might be off in some cases.

Note by the way that sizeof (max_align_t) might not be the same
as _Alignof (max_align_t).
