Subject: offsetof and XtOffsetOf
From: levim@php.net (Levi Morrison)

Content-Type: text/plain; charset=UTF-8

The macro offsetof is required by the C89 standard to be defined in
stddef.h and remains in newer standards. The macro XtOffsetOf is
non-standard that is as far as I can tell a part of the X Toolkit
Intrinsics or Xlib.

Does anyone know the reasons why we are using the non-standard macro
instead of the standard one?
