boost.smart_ptr clashes with PAM

[SebastianLuther@…]

The following test case (reduced from drizzle [1]) compiles fine with with boost-1.46.1 and failes with boost-1.47.0.

$ cat test.cpp 
#include <security/pam_misc.h>
#include <boost/shared_ptr.hpp>
int main() {}


$ g++ test.cpp 
In file included from /usr/include/boost/smart_ptr/shared_ptr.hpp:32,
                 from /usr/include/boost/shared_ptr.hpp:17,
                 from test.cpp:2:
/usr/include/boost/smart_ptr/detail/shared_count.hpp: In constructor 'boost::detail::shared_count::shared_count(P, boost::detail::sp_inplace_tag<D>)':

security/pam_misc.h belongs to PAM [2]

It actually collides with a macro #define D(x) defined in security/_pam_macros.h.

Replying to SebastianLuther@…:

It actually collides with a macro #define D(x) defined in security/_pam_macros.h.

Looks like a bug in PAM. It should not define macros with such common and simple names.
