2905 the UNIX child status has some relationship to errno values, so
2906 Perl tries to translate it to text in some of the tests.
2907 In order to get the string translation correct, for the error, errno
2908 must be EVMSERR, but that generates a different text message
2909 than what the test programs are expecting. So an errno value must
2910 be derived from the native status value when an error occurs.
2911 That will hide the true native status message. With this version of
2912 perl, the true native child status can always be retrieved so that
