Well, don't quite like this solution since it's not immune to simple 
file rename. But I started to think (yes, following comrade major 
scheme) and eventually and inevitably came to conclusion that

#declare extension = substr(input_file_name, strlen(input_file_name) - 3, 4)

#debug extension

shows me

.pov

and even subsequent

#if (extension = ".pov")
   #debug "Match!\n"
#end

says "Match!"

Combining it with your suggestion, I guess I can produce files that work 
as a whole scene when they are .pov, and as include after renaming to .inc

But this is not confirmed experimentally yet ;-)
