[aspectc-user] introductions into sourcefiles

[Olaf Spinczyk]

Hi Martin,

the mechanism works with any class, because the code is simply inserted 
into the .cc and .h file of the target class. The only condition is that 
there already has to be a .cc file for the class that already contains 
the definition of at least one non-inline member function or static 
attribute definition. Otherwise the weaver would complain.

If it still does not work, post  a simple example.
