It is. Thanks for this test, the result is as horrifying as I imagined. Can you please try the testcase attached to this mail, too? It should be built and run the same way: $ gcc -g -o azure-check2 azure-check2.c -lnetapi32 $ ./azure-check2 Thanks, Corinna -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Maintainer cygwin AT cygwin DOT com Red Hat
