AFAICT, no Lisp actually supports "long long", or if they do it's
undocumented.
Trying to use a struct with two longs won't work, among other reasons,
because we pass structs by reference. So, you were actually trying to
fit a long long in a pointer (an int), and then dereferencing that.
CLISP allegedly supports an :[us]int64 type, but I couldn't get it to
work under either linux/x86 or darwin/ppc. I suppose it only works on
64bit platforms? I guess you're out of luck there too.
All I can think of is ugly C glue to split long long into two longs
(pretty much what you intended to do using a struct). You should
probably ask your lisp vendor for long long support. :-/
