Thanks to all who responded - clearly that code is not what I
needed. Fortunately Neil's code appears to work, and is simple enough
that even I can understand how it works... Thanks Neil. :)
Searching around a little more I found a test for this in a proposed
update to autoconf:
offsetof (struct { char x; $1 y; }, y)
(Where $1 is the type to test)
Same basic concept as the code proposed here, and since it was written
to be part of autoconf, I just extracted the entire test and it appears to
work well in aclocal.m4.
Thanks again!
