there seems to be a bug in ac++ occurring when used with the systemc 
library. This bug avoids the generation of forward declarations for 
advice functions causing the advice function to be used before it is 
declared. The systemc library forward declares the sc_main() function 
and applying advice to sc_main() will trigger this bug. But, as a first 
approach, you can #define the macro SC_EXTERNS_H before including the 
systemc headers avoiding the forward declaration of sc_main() to be parsed:

#define SC_EXTERNS_H
#include <systemc.h>

The linker problems seem not to be caused by ac++ for me, but you can 
run ag++ using the -v9 option to gather more information about what ac++ 
does and what problems the compiler has.

By the way, the backward warnings printed by ac++ can be disabled by 
removing or commenting the __DEPRECATED define in the puma.config file:
