2918 the UNIX child status has some relationship to errno values, so
2919 Perl tries to translate it to text in some of the tests.
2920 In order to get the string translation correct, for the error, errno
2921 must be EVMSERR, but that generates a different text message
2922 than what the test programs are expecting. So an errno value must
2923 be derived from the native status value when an error occurs.
