Hello,

I am having big trouble migrating from 1.65.1 to 1.67 in VS2008 for CE
platform. We already have quite a few patches for boost we reapply on every
update. Boost 1.67 added more issues here and there, and among them the
winapi library.

On our old CE 7.00 I have winnt.h file where the second branch get selected.

#if (defined(_M_MRX000) || defined(_M_IX86) || defined(_M_ALPHA) ||
defined(_M_PPC) || defined(_M_IA64)) && !defined(MIDL_PASS)
#define DECLSPEC_IMPORT __declspec(dllimport)
#else
#define DECLSPEC_IMPORT
#endif

Therefore, WINAPI functions are not imported but is linked via corelib.lib
library.

So when I compile my code I see
3>D:\Dev\boost167\boost/winapi/semaphore.hpp(48) : error C2375:
'CreateSemaphoreW' : redefinition; different linkage
3>        C:\Program Files (x86)\Windows CE
Tools\SDKs\DS-200i\include\ARMv4I\winbase.h(3189) : see declaration of
'CreateSemaphoreW'

To make things worse in Windows Mobile 6 SDK half of API is imported and
half is not (goes through corelib.lib). Visual Studio 2008 installer
includes WM6 SDK.  And in the file
C:\Program Files (x86)\Windows Mobile 6
SDK\PocketPC\include\ARMV4I\winbase.h
there are functions not prefixed with WINBASEAPI.

The solution would be to have 2 new defines instead of BOOST_SYMBOL_IMPORT in
boost::winapi.  On CE 7 both would be empty, on WM 6 one would be
__declspec(dllimport)

Vyacheslav
