 Hi,

 I've got a problem with compiling an extremely simple program on one
 machine while there is no problem on another one. The program is:

 {{{
 #include <boost/asio.hpp>
 #include <boost/mpi.hpp>
 #include <boost/interprocess/sync/interprocess_semaphore.hpp>
 int main(){ return 0; }
 }}}


 I get these errors:

 {{{
 /usr/local/include/boost/interprocess/detail/os_file_functions.hpp:363:33:
 error: ‘SEEK_SET’ cannot appear in a constant-expression
 /usr/local/include/boost/interprocess/detail/os_file_functions.hpp:364:33:
 error: ‘SEEK_END’ cannot appear in a constant-expression
 /usr/local/include/boost/interprocess/detail/os_file_functions.hpp:365:33:
 error: ‘SEEK_CUR’ cannot appear in a constant-expression
 }}}

 Only this order of includes causes the problem, changing the order makes
 compilation complete successfully and the program (along with a more
 complicated one) runs fine.

 The error happens on my Ubuntu 11.04 (natty), kernel: 2.6.38-8-generic,
 gcc (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2 .
 It doesn't happen on my other machine with the same version of boost and
 any ordering of the includes, it runs Ubuntu 10.04.2 LTS (lucid), kernel:
 2.6.32-30-generic, with gcc (Ubuntu 4.4.3-4ubuntu5) 4.4.3 .
