2649 status which must be saved. But there is an assumption in Perl that
2650 the UNIX child status has some relationship to errno values, so
2651 Perl tries to translate it to text in some of the tests.
2652 In order to get the string translation correct, for the error, errno
2653 must be EVMSERR, but that generates a different text message
2654 than what the test programs are expecting. So an errno value must
2655 be derived from the native status value when an error occurs.
2656 That will hide the true native status message. With this version of
2657 perl, the true native child status can always be retrieved so that
2658 is not a problem. But in this case, Pl_statusvalue and errno may
2659 have different values in them.
