2625 the UNIX child status has some relationship to errno values, so
2626 Perl tries to translate it to text in some of the tests.
2627 In order to get the string translation correct, for the error, errno
2628 must be EVMSERR, but that generates a different text message
2629 than what the test programs are expecting. So an errno value must
2630 be derived from the native status value when an error occurs.
2631 That will hide the true native status message. With this version of
2632 perl, the true native child status can always be retrieved so that
2633 is not a problem. But in this case, Pl_statusvalue and errno may
2634 have different values in them.
