The SZ_FRAME AL_FRAME SZ_TOP SZ_BOTTOM is not used for anything serious
and can be left alone in a port. They were included for a (now defunct)
version of cfront that was to generate assembly code directly.

The rest of the sizes and alignments can be found without too much trouble
by writing a few C programs for the target machine.

In general, before porting C++ have a look at Jonathan P. Leech's
article about porting release 1.0 "Article-I.D.: cit-vax.278"

He is: jon@cit-vax.UUCP from California Institute of Technology.
It contains a lot of good stuff.
