2879 the UNIX child status has some relationship to errno values, so
2880 Perl tries to translate it to text in some of the tests.
2881 In order to get the string translation correct, for the error, errno
2882 must be EVMSERR, but that generates a different text message
2883 than what the test programs are expecting. So an errno value must
2884 be derived from the native status value when an error occurs.

2886 perl, the true native child status can always be retrieved so that
