2637 the UNIX child status has some relationship to errno values, so
2638 Perl tries to translate it to text in some of the tests.
2639 In order to get the string translation correct, for the error, errno
2640 must be EVMSERR, but that generates a different text message
2641 than what the test programs are expecting. So an errno value must
2642 be derived from the native status value when an error occurs.
2643 That will hide the true native status message. With this version of
2644 perl, the true native child status can always be retrieved so that
2645 is not a problem. But in this case, Pl_statusvalue and errno may
2646 have different values in them.
