No, only if you don't change the tokenization.  For example, if you remove
the whitespace in "int i;", you will change the meaning of the statement.
Similarly for "a / *b", or "a - -b".

Indeed, and this contradicts your previous statement.  If whitespace didn't
matter, this would be ambiguous between "a + ++b" and "a++ + b".
