Note that there is not yet any linkage involved -- this is simply a compile
pass. Specifically, the problem here is that I run into a missing symbol error
when linking a program that does use the symbol.

I'm pretty sure that the C++ standard does not specify that separate
compilation should break unless all const variables are used in the compilation
unit where they are defined.

I will attach the preprocessed source.
