Add a trivial test for the compiler package, guarded by compiler resource.

This test is insanely slow, so it requires a resource.  On my machine,
it also appears to dump core.  I think the problem is a stack
overflow, but haven't been able to confirm.

 example, to run all the tests except for the bsddb tests, give the
 option '-uall,-bsddb'.
