2630 the UNIX child status has some relationship to errno values, so
2631 Perl tries to translate it to text in some of the tests.
2632 In order to get the string translation correct, for the error, errno
2633 must be EVMSERR, but that generates a different text message
2634 than what the test programs are expecting. So an errno value must
2635 be derived from the native status value when an error occurs.
2636 That will hide the true native status message. With this version of
2637 perl, the true native child status can always be retrieved so that
2638 is not a problem. But in this case, Pl_statusvalue and errno may
2639 have different values in them.
