2.95.1 nested classes broken

[raymond at magma dot magma-da dot com]

Dear gcc maintainers,

In gcc-2.95.1 the scoping of nested classes is broken.   The snippet below
compiles with gcc-2.7.2, egcs-1.1.2 and a wide variety of newer commercial
C++ compilers, but it fails on 2.95.1.

Thanks,
-Raymond
