are there any really compelling reasons to need to know the offset
of a structure field? just curious.
I don't much about that macro. Anyway I came across a couple of articles
from which I have a vague idea of why it is used.

Mostly, if the project is of ANSI standard, then it is just there for
standards compliance. Otherwise, the macro is used for the reasons
mentioned here in this article
