9305	Errors when building Boost with MinGW	Ben Key <BKey76@…>	Andrey Semashev	"When building the latest Boost SVN with MinGW I am getting the following errors.

./boost/detail/winapi/thread_pool.hpp: At global scope:
./boost/detail/winapi/thread_pool.hpp:30:9: error: '::RegisterWaitForSingleObjectEx' has not been declared
 using ::RegisterWaitForSingleObjectEx;

./boost/sync/detail/waitable_timer.hpp: In member function 'void boost::sync::detail::windows::waitable_timer_state::init()':
./boost/sync/detail/waitable_timer.hpp:169:26: error: 'OpenSemaphoreA' is not a member of 'boost::detail::winapi'
         tls_key_holder = boost::detail::winapi::OpenSemaphoreA
         
The solution to the OpenSemaphoreA error is to simply add the following line to boost\detail\winapi\synchronization.hpp.
    using ::OpenSemaphoreA;

I added it immediately after the ""using ::CreateSemaphoreA;"" line.

The solution to the RegisterWaitForSingleObjectEx error is a little more complicated. There is a bug in the mingw-w64 version of winbase.h. It does not define RegisterWaitForSingleObjectEx. The solution is to replace the ""using ::RegisterWaitForSingleObjectEx;"" line with the following,

#if defined(__MINGW32__)
/* Work around a bug in the mingw-w64 version of winbase.h which does not define RegisterWaitForSingleObjectEx */
WINBASEAPI HANDLE WINAPI RegisterWaitForSingleObjectEx(HANDLE,WAITORTIMERCALLBACK,PVOID,ULONG,ULONG);
#else
using ::RegisterWaitForSingleObjectEx;
#endif


The following patch resolves these issues and an issue with the bootstrap process I reported earlier,
