I’m sure it does _not_ do all those uber-optimisations, and I believe
that “it made sense last century but not now” is wrong for easy, low‐
hanging fruits like shifts and bitmasks (but that prematurely writing
complex stuff that makes code illegible is still undesirable).

In traditional syntax ' is ignored, but in c99 everything between two ' is
handled as character constant.  Therefore you cannot use ' in a preproces-
sing file in c99 mode.	-- Ragge
No faith left in ISO C99, undefined behaviour, etc.
