/MEMBER_ALIGNMENT

    /MEMBER_ALIGNMENT (D)
    /NOMEMBER_ALIGNMENT

 Directs the compiler to naturally align data structure members.
 This means that data structure members are aligned on the next
 boundary appropriate to the type of the member, rather than on the
 next byte.  For instance, a long variable member is aligned on the
 next longword boundary; a short variable member is aligned on the
 next word boundary.

 Any use of the #pragma member_alignment or #pragma
 nomember_alignment directives within the source code overrides the
 setting established by this qualifier.  Specifying
 /NOMEMBER_ALIGNMENT causes data structure members to be
 byte-aligned (with the exception of bit-field members).

 For 64-bit systems, the default is /MEMBER_ALIGNMENT.

 For OpenVMS VAX systems, the default is /NOMEMBER_ALIGNMENT.
