[Bug c++/14397] New: Trules no longer compile (regression)

[schmid at snake dot iap dot physik dot tu-darmstadt dot de]

The following code, t.C, taken from the file pointers/truletest.cpp from the 
book C++ Templates - The Complete Guide by David Vandevoorde and Nicolai M. 
Josuttis, does no longer compile. It worked when last tried approximately a 
week ago. gcc 3.3 accepts this code without a problem. 
 
I appologize if this is a bogus bug report.
