h2pas translates it to a record with associated setters/getters for each
field.
You could also try with bitpacked records, i.e.
type MyStruct = bitpacked record
a:0..(1 shl 6)-1;
b:0..(1 shl 15)-1;
c:0..(1 shl 11)-1;
end;
but, as Jonas said, it't not guaranteed to work (in practice it works
with win32/linux 32 and linux 64, though it could break with a different
version of the compiler).
