2647 the UNIX child status has some relationship to errno values, so
2648 Perl tries to translate it to text in some of the tests.
2649 In order to get the string translation correct, for the error, errno
2650 must be EVMSERR, but that generates a different text message
2651 than what the test programs are expecting. So an errno value must
2652 be derived from the native status value when an error occurs.
2653 That will hide the true native status message. With this version of
2654 perl, the true native child status can always be retrieved so that
2655 is not a problem. But in this case, Pl_statusvalue and errno may
2656 have different values in them.
