 This doesn't ICE any more with mainline, but with James's smaller 
 #include <cstddef>
 template< typename T, size_t N >
 size( T (&a)[ N ] )
   return N ;
   static char const   s[] = "abc" ;
   int                 buf[ size( s ) ] ;
   size_t              r = size( buf ) ;
 I now get:
 g/x> /home/bangerth/bin/gcc-3.4-pre/bin/c++ -c In function `void f()': error: no matching function for call to `size(int[size(T (&)[N]) 
    T = const char, unsigned int N = 4]((&s))])'
 I think, it's warranted that gcc doesn't find a match, since "buf" is 
 dynamically sized (there are other duplicates of this problem). It's 
 funny, though, that gcc is able nevertheless to figure out the size of the 
 array, and the error message of course is not very helpful:
 - it says that there's no match, even gives the template args, where there
   of course is one.
 - the placing of the template args is wrong in the message.
 Nathan, can you say anything about the legality of this at least?
