Remove unused #define PERCENT_OF_SCREEN in MyWindow.h Move structures for dir.c to dirdefs.h where they are used Resolve S_CHAR vs S_CHARACTER in favor of S_CHARACTER and cleanup #defines Fix = vs == bug in FSDEBUG code in dir.c Eliminate duplicate/unused constant definitions in gcr.c Declare static internal function bytecmp in mkatom.c Update many source and include files to include headers for what they use
