 AFAIK, they are macros as far as pop_macro is concerned. If you see a
 problem then please provide a test case.

 The following source file "test.mm":

 {{{
 #include <boost/asio.hpp>
 #ifdef Protocol
 # error Protocol is defined
 #endif
 #ifdef id
 # error id is defined
 #endif
 }}}

 compiles without error or warning using gcc 4.4.5.
