Okay, it looks like most of the problems are caused by the fact that the
GCC internal to GCC-XML is defining __STDC__ and __MINGW32__, but MSVC
does not define them.  I've updated the simulation flags to use
"-U__STDC__ -U__MINGW32__" to remove these flags.  This takes care of
most of the errors.  There was one problem in VS's process.h that I had 
to fix and add to the GCC-XML header patching.  Both of these changes 
are now in CVS.

The last error is in ace/OS_NS_time.inl.  You'll have to patch this 
header on these lines:

// Linux won't compile unless we explicitly use a namespace here.
#if defined (__GNUG__)
namespace ACE_OS {
   ACE_INLINE long
   timezone (void)
   {
     return ::ace_timezone ();
   }
} /* namespace ACE_OS */
#else
ACE_INLINE long
ACE_OS::timezone (void)
{
   return ::ace_timezone ();
}
#endif /* linux */

This works around a bug in GCC's parser.  We need to make sure this 
work-around is still used.  Change the first line to

#if defined (__GNUG__) || defined (__GCCXML__)
