[PD] x_list for pd 0.37

[volker böhm]

hello,
quite a retro-question, but maybe someone can help:
currently i'm working with PDa on a gumstix computer.
PDa is based on pd 0.37.4 and it doesn't contain the list objects.
since i do a lot of list processing, it would be nice to have those  
on the gumstix, too.
so, i took the source (x_list.c) from a recent version, cross  
compiled it for the gumstix and installed the object in /usr/lib/pd/ 
externs.
this is working fine.
only drawback is, that everytime i run pd, i have to create a  
[x_list] object before i can use any of the list objects, like [list  
append], [list trim] etc. so i have to somehow load the object into  
memory. not a big issue, but can be annoying.
in newer versions of pd this is done automatically.
(i guess you call this an "interal" as opposed to "external"?)

how could i apply the same auto-load mechanism in this situation?

thanks for your comments,
volker.
