724bbec47f86 Use a new fatal_error function instead of calling fprintf and exit for fatal errors. This new function more gracefully handles the case in which BlastEm was not started from a terminal or disconnected from ther terminal (Windows).

a7774fc2de4b Partially working change to do proper stack alignment rather than doing a lame alignment check when calling a C compile dfunction. 68K core seems okay, but Z80 is busted.
