>Description:
Define a struct in a member template in a template class 
gives internal compiler error.  
>How-To-Repeat:
g++ template_struct_bug.ii
>Fix:
This is byzantine but correct code AFAIK.  One work around
is to use typedefs.  However, I run into it writing library 
classes employing STL and threads.  The pthread_cleanup_push
macro defines a struct _pthread_cleanup_buffer, which triggers 
the problem.  One can hack pthread.h, but this really seems
to be a compiler problem.
