>Description:
I have tried using aix compiler version 3, 4, and 5 to compile decl.c. 
Every line that has this defined ternary as an lvalue fails to compile.

>How-To-Repeat:

>Fix:
change this define to the following

#define current_binding_level                   \
  (*(cfun && cp_function_chain->bindings                \
   ? &cp_function_chain->bindings               \
