2632 the UNIX child status has some relationship to errno values, so
2633 Perl tries to translate it to text in some of the tests.
2634 In order to get the string translation correct, for the error, errno
2635 must be EVMSERR, but that generates a different text message
2636 than what the test programs are expecting. So an errno value must
2637 be derived from the native status value when an error occurs.
2638 That will hide the true native status message. With this version of
2639 perl, the true native child status can always be retrieved so that
2640 is not a problem. But in this case, Pl_statusvalue and errno may
2641 have different values in them.
