! PR30005 Enhanced error messages for OPEN
! Submitted by Jerry DeLisle  <jvdelisle@gcc.gnu.org>
! See PR38956.  Test fails on cygwin when user has Administrator rights
! As of the fix for PR 65200, the error message is partly generated by
! strerror*(), so can depend on the target and the locale, so check
! only the beginning of the error string, which should be constant.
