Tou use a research term, "thats just ka-ka" :)
Packed in no way solves the problem of selecting the appropriate types.

no, it's not ka ka at all. I had huge troubles with plan 9 c and the way
that the linux structs were packed via the use of gcc struct packing. I
am really glad packed went away.


I think you misunderstand: Jimi is also glad. Read again: the packed GCC attribute does not solve the problem.


That figures. I am really sorry it's monday.

thanks

ron
p.s. jimix, whereever you may be, I'm sorry.
