as `packed'. The C standard leaves the alignment of individual members of a C struct upto the implementation, so pedantically speaking portable code cannot assume that the layout of a `struct ar_hdr' in memory will match its layout in a file. Using a __packed attribute declaration forces file and memory layouts for this structure to match. Submitted by: ru
