I think I understand why the sizes were hardcoded: this, plus the
endian flags, allows you to pack bytes in one architecture and unpack
them in another with the same format string (so you can send the
packed information via the network, for example). You can still do
that in the new struct.c using the i<n> format code, though, and this
is probably why Roberto changed h/H and l/L to use the native sizes.
