i686 RH linux 2.4.2-2 (kde 2.1.1) :
queue.c: In function `icq_UDPQueueFindSeq':
queue.c:130: `WORD' is promoted to `int' when passed
through `...'
queue.c:130: (so you should pass `int' not `WORD' to
`va_arg')
make[2]: *** [queue.lo] Error 1m
it would compile after changing WORD for int in the
call to va_arg...
