comdef.h compiler error

I have a VC++ project that I want to use a COM library in. So, I import
my COM dll with an absolute path (since it's in my VS project
directory) like this.

#import "C:\\...\\MyDLL.dll"

But, when I go to compile my project that uses that COM DLL, I get an
error in comdef.h. This error doesn't appear when I don't import, and I
have no trouble compiling and registering the DLL itself.

Error 1 error C2589: '(' : illegal token on right side of
'::' C:\...\comdef.h 240
Error 2 error C2059: syntax error : '::' C:\...\comdef.h 240
Error 3 fatal error C1903: unable to recover from previous error(s);
stopping compilation c:\...\windows mobile 5.0 pocket pc sdk

The actual comdef.h line is:

inline const TCHAR * _com_error::ErrorMessage() const throw()
{
if (m_pszMsg == NULL) {

FormatMessage(FORMAT_MESSAGE_ALLOCATE_BUFFER|FORMAT_MESSAGE_FROM_SYSTEM,
NULL,
m_hresult,
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT),
(LPTSTR)&m_pszMsg,
0,
NULL);
if (m_pszMsg != NULL) {
int nLen = ::lstrlen(m_pszMsg); //compiler error here!
//...
}

Is there a setting, or something I'm missing to get this to work that
anybody can see?

Thanks,
