Sorry about that. It appears I just stumbled over a Cygwin bug in terms of casesensitivity when using the execp family of functions. Just calling `cygdrop -p SeBackupPrivilege attrib' without full path should be fine, but it only works on systems which are not configured for casesensitivity. I'll fix that in CVS.
