not supported by dump decl?

[Peter Schmid <schmid at ltoi dot iap dot physik dot tu-darmstadt dot de>]

While compiling the following file the compiler emits the message:
sorry, not implemented: `reference_type' not supported by dump_decl.
The first definition of the function rev is taken from the file
reverseBidirectionalIterator.html of SGIs STL homepage, so I thought
the function should compile.
The second version of rev by me works, though.

Is this behaviour a compiler bug or has the standard changed?
