i#7718 offsetof: Add verbose warnings for deprecated options (#7742)

Modern C++ compilers give a warning when offsetof() is used with
structs containing non-POD fields. Consequently we removed the
struct size check with its error return and now just output a
warning when deprecated fields are used.

Issue: #7718
