But I might consider it as an interim solution. Regardless, this is something for somebody who cares about these cases to write a patch for. In real life this really isn't important. Change the status when you come up with a patch. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
