Windows NT, service pack 4
>Description:
The compiler does not accept the following code:

template <class C>
class Array
{};

typedef struct { struct { } Array; } TESTSTRUCT;

It appears to interpret the token "Array" in the last line to refer to the template class declaration above. The problem does not occur when class Array is not declared as a template class or when the inner struct{} is replaced by a simple type.

The problem occurred originally in the file "winnt.h" in the MinGW distribution of GCC 3.1 for some code where a template class Array was also defined before including "winnt.h".
>How-To-Repeat:
Compile the five code lines in the description with g++ 3.1.

Unknown
