2899 status which must be saved. But there is an assumption in Perl that
2900 the UNIX child status has some relationship to errno values, so
2901 Perl tries to translate it to text in some of the tests.
2902 In order to get the string translation correct, for the error, errno
2903 must be EVMSERR, but that generates a different text message
2904 than what the test programs are expecting. So an errno value must
2905 be derived from the native status value when an error occurs.
2906 That will hide the true native status message. With this version of
2907 perl, the true native child status can always be retrieved so that
2908 is not a problem. But in this case, Pl_statusvalue and errno may
