 Is that so? (Harmlessly asking.) - I mean, if I write  int x = -5;
does it matter (in "C") whether its parsed as  <integer number>  or
  <negation> <positive number> ?
 

I can't think off-hand of any situation in which it would matter, but maybe others can.  (It's also worth noting that there were changes in the way integer constants were typed between C90 and C99 - though usually the differences are harmless.)

I faintly recall a discussion, I think in context of exponentiation.
 But I don't want to (re-)open a can of words...
 

Too late for that!
