[Boost-users] Issues with unnamed enums

I have just tried to use Boost for the first time and it appears to
not take kindly to unnamed enums from another library I use and (once
those were named) some Microsoft SDK.  I am using:

Windows XP SP3
Visual Studio 2008 SP1
Boost 1.41.0

More specifically, after adding '#include <boost/foreach.hpp>' I
started getting compilation errors such as:

1>c:\korvis\boost\include\boost\iterator\iterator_facade.hpp(43) :
error C2332: 'class' : missing tag name
1>c:\korvis\boost\include\boost\iterator\iterator_facade.hpp(43) :
error C2011: '<unnamed-tag>' : 'enum' type redefinition
1>        c:\korvis\korvislibs\khmilib\kvdisplay.h(18) : see
declaration of '<unnamed-tag>'
1>c:\korvis\boost\include\boost\iterator\iterator_facade.hpp(43) :
error C2143: syntax error : missing ',' before 'constant'

kvdisplay.h(18) is the definition of an unnamed enum in another
library I use.  iterator_facade.hpp(43) is (including comments before
it):

> // This forward declaration is required for the friend declaration
> // in iterator_core_access
> template <class I, class V, class TC, class R, class D> class iterator_facade;

I went through and named a each of the unnamed enums as the compiler
referenced them until I got to an issue with shlwapi.h from a
Microsoft SDK.  Here's the complete compiler error list at that point:

1>c:\korvis\boost\include\boost\iterator\iterator_facade.hpp(43) :

Am I correct that the unnamed enums are somehow causing the problem?
Any help you can offer understanding or resolving this issue would be
greatly appreciated.

Thanks for your time,
