It seems that the grammar for conditional preprocessor expressions was not updated when long integer literals were added for C++11. This seems to work most of the time, as they get recognized as PP_NUMBER tokens, which are in the grammar. Sometimes, though, when they are produced as part of a macro expansion, they can appear as LONGINTLIT tokens, which are not in the grammar. Wave then rejects the expression as invalid.
These changes add LONGINTLIT tokens as valid numbers in expressions, and in doing so resolve #162
