bug in egcs-1.1.2 compiling C++ code on linux/x86 - nested classes in template class partial specialization

[John Pedretti]

Compilation of the following (legal C++) code results in a bogus error
message (included below). The problem arises in the declaration of a
partially specialized template class which contains a nested class with a
constructor. It doesn't look like this is documented as a "well-known bug"
so I thought you might want to know about it. 

BTW, is there any chance that this bug is fixed in gcc-2.95?

Cheers, John
