In most cases, it will probably be ok to do so.

However, if the original source file is not available, it would not
make sense to do so.  

In a few cases, files may have been autogenerated at some point in
time, but manually edited since - leaving some old #line directives in
the file.  But in this case, those #line directives doesn't make sense
(they would make a compiler output bogus error references), so in this
case the user should actually remove those lines.

So I would say: yes, let emacs handle #line - if the source file is
readable (and older than the current file) -- and if it is in a format
which is supported by etags.
