Compiler food.

main.c: In function ‘RelaunchWindow’:
main.c:461:1: warning: control reaches end of non-void function
[-Wreturn-type]

Actually we can't reach the end of the function because the three
possible cases are Exit(-1), return False and return True.  Of course if
Exit() were ever changed the above statement might become incorrect.
Some compiler food silences the warning.
