Those last two seem to rather pointlessly do almost exactly the same thing, differing only in whether the initial $# is provided by the user or the system. Cog-world seems to have only the cPreprocessorDirective: version and no uses of it; plain-interp-world has both and has no uses of cPre… and a single 'real' use of preprocessorExpression: and a single 'testing' usage.

There's also a bunch of related code in FT2PluginCodeGenerator where it adds its own translation fooblies.
