Initializing a union containing a nameless struct as one of its
members will cause the following compiler errors:

   error C2097:   illegal initialization

   error C2078:   too many initializers

The sample code shown below reproduces the problem:

union
{
   struct
   {
      int a;
      int b;
   };            // Add a name here to allow initialization
   long c;
} x = {{ 0,0 }};

The only workarounds available are to either name the struct or to
leave the union uninitialized.

Microsoft has confirmed this to be a problem with Microsoft C version
6.00. We are researching this problem and will post new information
here as it becomes available.
