This depends however on the code you're interfacing with. Also the
record you mentioned as an example shouldn't differ with and without
packed anyway...
With packed the above record is 13 bytes, without is 16 (the bytes are
word aligned).
That's with fpc 2.6.4 x86_64 (though it should be the same with a 32
bits compiler).
Just to be sure, in such cases I also use "packed array" and most of the
times bitpacked records.
