You have quite precisely missed my point.  It was even in quotes.  Briefly:
   1)  "comment out a section..."      Use comments.
   2)  "compile if x {not} defined"    Use #if{n}def/#endif.
See the difference?  In particular, I did not say that nested comments are
the better way to suppress the compilation of a section of code. If it's a
comment it isn't code!  The notion of conditionally compiling comments is
a bit off the mark, IMHO.  Comments are never compiled--nothing conditional
about that.  Lexed or parsed maybe, but not compiled.
  It isn't a religious issue. It is a semantic issue--on two levels, no less.
On the lower level, what I said is not what you thought I meant.  On the
higher level, #ifdef/#endif and nested comments are not the same although
the end result may be the same.
