Well, it's not my testsuite, but yes, I'm running under administrator account. But it makes me wonder, how does it work? Do you change ACLs temporarily? Anyway, it means there is a bug in perl, because on Linux: root@kitsu:~# touch test.txt root@kitsu:~# chmod 0444 test.txt root@kitsu:~# perl -e 'print "writable\n" if -w "test.txt"' writable On Cygwin 1.7 perl thinks that the file is not writable. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
