Well I found the ar specification (in ar.5 not ar.1).
struct ar_hdr {
char ar_name[14];
long ar_date;
char ar_uid;
char ar_gid;
int ar_mode;
long ar_size;
};
Endian should not be a problem on a Intel/AMD processor. More likely your C
compiler is padding out the array for alignment. Try a '-fpack-struct' or
more safely, read the elements individually rather than a structure.
PS
To check, see what 'sizeof (struct ar_hdr_)' returns.

Well, you are correct in that aligment is a part of the problem.
However, endianess is also a problem with longs, since they are not
little-endian on a PDP11. :-)
