   Have you tried this in protected and/or kernel build modes. There might be problems when writing to the errno in those cases since the errno resides in the TCB which is not accessible.  In those modes set_errno() is a function call that goes through a syscall and error is defined to be get_errno() which will only support read access.
   
   So reading the errno in the modes is okay, but writing must explicitly use set_errno().  That does break the standard but I am open to other technical solutions.
