zik.saleeba 95f2b3e193 Characters are now actually stored as char and coerced to other types when necessary.
Parameters are passed as the requested types and coerced where appropriate.
Assignments are now a function rather than a macro.
Cleaned up some comments in lex.c.
Small valued integer constants are passed as char constants to save space.

zik.saleeba 48a6472c68 All allocations are now cleaned up neatly on exit. This is probably unnecessary given that we run our own heap but gives confidence that there are no internal memory leaks.
