glibc's sunrpc/clnt_tcp.c contains code like this:

      *(u_long *)(ct->ct_mcall + 3 * BYTES_PER_XDR_UNIT)
              = htonl(*(u_long *)info);

ct->ct_mcall is a char[] array that's after a struct,
BYTES_PER_XDR_UNIT is 4

if sizeof(u_long) is 8, then this is an unaligned access... (gcc notices
and complains loudly :-)

this code apparently works on other 64-bit archs.... anyone know how?

They may not require strict alignment.
