I wonder, don't you usually do
c_af = (su_cs_find_c(pgp->pg_ca, ':') != NIL) ? AF_INET6 : AF_INET;
if(inet_pton(c_af, pgp->pg_ca,
(c_af == AF_INET ? S(void*,&c_sip.v4)
: S(void*,&c_sip.v6))) != 1){
Problem (for me regarding inet_pton(3)) is more that this beast
fails for things like 127.000.000.001, it expects properly
formatted 127.0.0.1. (This at least GNU LibC, i personally see
this as a bug, even though POSIX says "standard text
interpretation" --- but that surely is decimal and then
"compression" (to use the term for IPv4) should be applicable or
not.)
