The LL linked list library is not fully portable. When installing the LL
library on a particular system, slight modification to LL.h must be made
to avoid alignment problems. 

As is, the LL library runs on SUNs (cc or gcc compiled) and on a DEC 
(mips & gcc).

To adjust it for your particular system,
the size of s_list structure defined in LL.h must be made
equal to (or a multiple of) the largest  required aligment. Typically,
the type with the strictest alignment is double. It's rare to encounter
alignment of more then 16 (usually it's 2,4 or 8). The required alignment 
of variables of a  certain type depend on both the machine architecture and
the compiler, so be carefull. 

The required alignments can be found by checking output of malloc. However,
if  you
  1/ make sure that sizeof(s_list) is 8 or 16
  2/ test LL on doubles
and experience no problems you're most unlikely to have problems. 

To change sizeof(s_list) either modify the number of chars in the
'padding' field of s_list or change the type of 'size' to obtain the
right size. If the right size of s_list would be obtained without any
padding chars, comment out the field.
