2891 the UNIX child status has some relationship to errno values, so
2892 Perl tries to translate it to text in some of the tests.
2893 In order to get the string translation correct, for the error, errno
2894 must be EVMSERR, but that generates a different text message
2895 than what the test programs are expecting. So an errno value must
2896 be derived from the native status value when an error occurs.
2897 That will hide the true native status message. With this version of
2898 perl, the true native child status can always be retrieved so that
2899 is not a problem. But in this case, Pl_statusvalue and errno may
2900 have different values in them.
