- When the main() function returns directly or indirectly by way of

calling exit(), the IoErr() value set at this time will now be
  preserved until the program really returns control to the shell.
  This turned out to be easier to implement than I had originally
  thought, thanks to the fact that the atexit() functions are all
  invoked straight after the exit() call.

 - strtoimax(), strtoumax(), strtod(), strtof(), strtol(), strtoll(),
   strtoul() and strtoull() now count how many digits were converted.
   If that number is zero, then the conversion is considered to have
