Thu Sep 3 02:13:25 PDT 2009 Malcolm.Wallace@cs.york.ac.uk * Bugfix: #undef caused an infinite loop Ignore-this: 449791949546c4ffa141fe22ddfa34c5 Cause: #undef was being translated into a SymbolReplacement where the replacement is the same as the original identifier. This used to work, until we switched on recursive expansion of SymbolReplacements. Fix: Introduce a different HashDefine constructor (AntiDefined) to handle #undef, rather than piggypacking on SymbolReplacement.
