I committed some of your fixes. The biggest part which significantly alters gethostbyname_r() is not applied, I want someone to review it first. b.patch is a patch avainst today's svn.

Test program:
#include <netdb.h>
#include <sys/socket.h>
#include <stdio.h>
int main(int argc, char **argv) {
char buf[1024];
char **h_aliases;
char **h_addr_list;
struct hostent *h = gethostbyname(argv[1]);
if (!h) {
printf("NULL! h_errno:%d (%s)\n", h_errno, hstrerror(h_errno));
return 0;
}
printf("h_name:'%s'\n", h->h_name);
printf("h_length:%d\n", h->h_length);
printf("h_addrtype: %x %s\n", h->h_addrtype,
h->h_addrtype == AF_INET ? "AF_INET" :
h->h_addrtype == AF_INET6 ? "AF_INET6" :
"???"
);
h_aliases = h->h_aliases;
while (*h_aliases)
printf("alias:'%s'\n", *h_aliases++);
h_addr_list = h->h_addr_list;
while (*h_addr_list) {
printf("addr: 0x%08x '%s'\n", (int) *(uint32_t*)*h_addr_list,
inet_ntop(h->h_addrtype, *h_addr_list, buf, sizeof(buf)));
h_addr_list++;
}
return 0;
}
Before patch:

h_name:'cnn.com'
h_length:4
h_addrtype:AF_INET
alias:'²&9557;&0001041;²&9557;&0001070;&9618;²&9557;&0001041;&0001051;&9618;'
