#7220: gcc 4.6.2 warns about inline+dllimport functions
------------------------------+---------------------------------------------
 Reporter:  anonymous         |       Owner:  anthonyw
     Type:  Bugs              |      Status:  new     
Milestone:  To Be Determined  |   Component:  thread  
  Version:  Boost 1.50.0      |    Severity:  Problem 
 Keywords:                    |  
------------------------------+---------------------------------------------
 In boost/thread/future.hpp, the functions make_error_code() and
 make_error_condition() are declared as "inline BOOST_THREAD_DECL".  In
 MinGW GCC 4.6.2, this results in the functions declared as both inline and
 as dllimport, which causes GCC to emit warnings.  This bug is similar to
 ticket #4315.

 Test program:

 {{{
 #include <boost/thread.hpp>
 int main()
 {
     return 0;
 }
 }}}

 Compiled via:

 g++ -o test.exe test.cpp -IC:/boost/include/boost-1_50 -LC:/boost/lib
 -lboost_thread-mgw46-mt-1_50 -lboost_system-mg
 w46-mt-1_50
