* Diagnose trailing junk in numeric literals.Kaz Kylheku2015-04-142-14/+28
| | | | | | | * parser.l: Combining the handling of hex, octal and binary numeric literals into a single rule. Implementing an additional rule which diagnoses such tokens that have trailing junk. Thus, something like #x1F2AZ is now invalid syntax.
