- Parse unions, sets, function type, packed arrays and some more imporvements to the parser. Now it parses uVariable, uConsts and even SDLh.pas - Improve rendering of C code - Fix preprocessor issues, define "FPC" - Make pas2c convert unit along with its dependencies into corresponding .c files, so you just call it for hwengine.pas to convert the whole engine
