Last change on this file since 220 was 194, checked in by gregli@…, 13 years ago

ifdef'd out more unused code. Also added a tool for looking through the listing and the output of the precompiler to aid in finding dead code. Some changes in the files are to add annotations for the tool to avoid false positives.
