(this bug is a good example of why I think -Wnested-externs should be enabled
by -Wall or -Wextra, btw)

No it does not as there is only one g_iValue variable. The reasoning behind
using extern int g_iValue; is so it does not get into the global scope.
The reason why the C front-end works is because we have a non TU scope which we
add decls to and then look up global decls that way and get that decl instead
of creating a new one.

I don't have root access to the build machine and I can only use the version of
compiler which is installed there.
Also, I don't think the problem is related to target platform. It should be
reproduceable on all the platforms.
If you can't try it yourself, I can run the test on SunOS or Linux tomorrow.

First, this bug should be filed with Apple as you are using Apple's modified
compiler. Second 4.0.x is no longer being maintained, so please try 4.1.x.
