   I think etags should generate references for both files, the original

That would double the size of the TAGS file.  I don't think that this
would be a good way to go in general.  Generally speaking, if I have a
#line directive pointing to a non-existent file, you could have troubles
even with the compiler.  So the developer using etags will care about
having meaningful #line directives, and we should not be concerned about
this problem at all.  So: 

1) etags should honour #line directives in C and C++ languages
   unconditionally. 

2) If there are cases where one would want to use etags (but not using a
   compiler), then there sould be an option to disable this behaviour. 

3) No languages other than C and C++ should be affected by #line
   directives.
