My environment is Windows XP (Chinese version, 32bit)/MinGW/g++-4.5.0. The reason is that Sleep() parameter type mismatches. In boost/thread/win32/thread_primitives.hpp:

namespace boost
{
    namespace detail
    {
        namespace win32
        { ...
            extern "C"
            { ...
                __declspec(dllimport) void __stdcall Sleep(unsigned long);

while in boost/smart_ptr/detail/yield_k.hpp:

namespace boost
{
namespace detail
{
#if !defined( BOOST_USE_WINDOWS_H )
  extern "C" void __stdcall Sleep( unsigned ms );
#endif

It looks like "extern C" modifier will make the function ignore namespace declaration. This makes sense as the function is defined in another module where we can't export namespace constraints. We should correct the parameter type to stop the compiler warnings.

'unsigned long' is correct according to <wtypes.h>, reassigning to myself.

[Peter Dimov]

(In [62246]) DWORD is unsigned long, not unsigned int. Refs #4217.

[Peter Dimov]

(In [63826]) Merge [62246] to release. Fixes #4217.

Hello,

I am using Ubuntu, codeBlocks, , boost 1.46 in GCC 4.7 [ yield_k.hpp ] I get this error ' error : Sleep was not declared in this scope' tried #include <unistd.h> and Sleep to sleep, nothing worked. when I change it to sleep 'error:expected initializer before 'sleep how Do I resolve this issue ??
