[PATCH] Fix for FR #14924 (The POSIX access(2) function not available) (re-post)

Hello! My mail probably got lost in all the fuzz about goto, etc. So here's the patch again.. It will fix FR #14924 and someone else was also asking for this feature in an unrelated bug report which I can't remember the number of. access(2) will report correct permissions for files when using ACLs too (is_writeable() etc does not). Sascha, since you made the comment "access() not supported, because it is braindead and dangerous and gives outdated results", do you have any objections ? Should I go ahead and commit it or should I close the bug as Won't Fix ? /Magnus
