Hello,
I'm really sorry if this is a stupid question, but as far as I know, u_int64_t
defined in /usr/include/sys/types.h should *always* be
a 64 bit unsigned integer, right?
Seems there's a bug (or I need more and stronger coffee). Compiling a program
on a 64 bit system with -m32 gets the 64

That maybe the case but does rm -f remove all copies?
Nope so its behaviour is safe even with multiple hardlinks.
No. rm unlinks a file from a directory. If the file had no more
links, it is deleted as well.
There's no surprise at all on the behavior of rm with hard links.

No, traceroute send UDP messages by default.
