This is a feature, not a bug.

Nope.

Nope, not really.  Exported templates I think will make this work when
implemented and your code fixed to use it, if you want.

Welcome to C++.  Every use of a template must be able to see the
definition of everything it uses, the only exception is for exported
templates as I recall.  You fail to show the definition of
firstclass<int>::method(void) to secondclass.o.  This is wrong.  You
must show the defition to second.o, if you want to code in standard
C++.  As a undocumented g++ extension, you can also fix it by having
some file, any file have a use of firstclass<int>::method(void) and
have it be shown the definition for it, but this of course is
non-standard C++.
