This reminds me, there is one small problem with
linux/Documentation/Changes in reference to the version of libg++ you
should use. In the process of my recent upgrade I installed libc 5.2.18
and libg++ 2.7.1.4; I found that C++ programs then produced amazingly
bogus output. It turns out that libg++ 2.7.1.3 is what you should use
with libc 5.2.18; libg++ 2.7.1.4 _must_ be used with libc 5.3.x. The
Changes file should suggest libg++ 2.7.1.3 instead.
