Yes, I tried it in CC, and it works fine. G++ gives an error like:
main.o(.text+0xe):main.C: undefined reference to `Array<int>::Array(void)'

And what do you mean "move the template definition?" I've tried commenting
out template<class Etype> in the array.C file, and it still gave me the same
error. Specifically what changes would you recommend?
