Static members in templates in egcs-1.0.1

[dave madden]

 =>supernova% g++ -pedantic test.C
 =>test.C:6: warning: ANSI C++ forbids in-class initialization of
 =>non-const static member `mycounter'

I've been trying to find out for a while: does the C++ spec allow you
to define static consts in the class definition?  Egcs & g++ do, but
all the compilers I've tried on NT complain.  Here's what I'd like to
do:

template <class T> class foo {
	class bar {
		int		 xxx;
		T		 ttt;
	} ;
  public:
	static const size_t BAR_SIZE = sizeof(bar);
	static const int T_OFFSET = (int)(&((bar *)0)->ttt);
	// ... and various other address, padding, etc. calculations
} ;

Am I legal?

Thanks,
