ansifront is a utility that processes the data stream between c.prep(version 
19, see on rtsi) and c.pass1 or c.comp.  It converts the code stream on the 
fly so that a voidless compiler see's only int's, and a few other such 
compatibility things. Version .12 of it is the last, and it seems to work 
quit well.  The various CC's about are generally scripts, and modifying them 
to include ansifront, or c-opt2 or CnoY, all of which can further optimize 
the code.
