[aspectc-user] slice-class

[Panu Bloigu]

Hello.

I'm not sure if this helps, but check out the include guards in your 
aspect headers; both aspects are protected by the same include guards 
(#ifndef __TEST_AH__). The aspect header Test2.ah should probably have 
something like #ifndef __TEST2_AH__.

Anyway, I tried your code with proper include guards and weaving 
resulted in both classes containing both of the methods: print() and 
print2().
