My MFC project includes several modules and now I introduced another with access to WebServices. Since then I get the compiler error:
error C2872: 'CMutex' : ambiguous symbol
could be 'c:\program files\microsoft visual studio 8\vc\atlmfc\include\afxmt.h(105) : CMutex'
or 'c:\program files\microsoft visual studio 8\vc\atlmfc\include\atlsync.h(77) : ATL::CMutex'
Obviously both files have CMutex class defined and it is not the same. If ATL versiun would be the one this module needs, I could probably define the namespace with ATL::CMutex. But how can I tell the compiler that it should take the first version? It has no namespace specified!?
