Checkpoint parser development for lwcc Beginning of lemon based parser for C including all the infrastructure for calling the lemon generated parser. This requires a translation layer from the preprocessor token numbers to the lemon parser token numbers due to the fact that lemon wants to control the token numbers. Eventually when the lemon parser gets replaced with a hand crafted recursive descent parser, this translation will no longer be required. However, in the interest of getting things working sooner rather than later, using something like lemon is beneficial.
