Yes ... but that wastes a bit of storage, especially if you have several
thousand of these structures, and need to align to 32byte ...

As I can say "align this to 16 byte", I thought I'll ask whether I can say
"align this to 15 (module 16) byte", and maybe get the linker to use the space
before that for some odd data (like ASCIIZ-strings).

Well, thanks anyway.
