- The compiler was not pushing the SENTINEL value to the operator stack and popping it afterwards, so the expression parsing was getting messed up. Now fixed.
- Also added targets to the Makefile to allow the emulators to be run directly (make xvic, make x64, make mame).
- Evaluating 'naked' array name `A` gives pointer to payload (same as `&A` or even `&A[0]`)
- Improved loading message in VM
- Got array pass-by-reference to work in compiler
- Fixed eval stack leak in array initialization code generated by compiler
