Summary: Compile failure on AMD64

Initial Comment:
This problem appears related to the following thread,
at least that is where soem compiler warnings were
first noticed.

http://openser.org/pipermail/devel/2005-November/001122.html

On an AMD64 based machine, the following compile
failure happens:

Compiling items.c
gcc -g -O9 -funroll-loops  -Wcast-align  -Wall 
-minline-all-stringops -falign-loops   -Werror   
-DNAME='"openser"' -DVERSION='"1.1.0-dev4 "'
-DARCH='"x86_64"' -DOS='"freebsd"' -DCOMPILER='"gcc
3.4"' -D__CPU_x86_64 -D__OS_freebsd
-DCFG_DIR='"/usr/local/etc/openser/"' -DPKG_MALLOC
-DSHM_MEM  -DSHM_MMAP -DDNS_IP_HACK -DUSE_IPV6

-DHAVE_CONNECT_ECONNRESET_BUG -c items.c -o items.o
items.c: In function `xl_get_content_length':
items.c:908: warning: cast from pointer to integer of
different size
gmake: *** [items.o] Error 1


The simple test program below was run on both Intel and
AMD processors

#include <stdio.h>
main() {
  char *ptr;
  printf("Size of int: %d\n", sizeof(int));
  printf("Size of char: %d\n", sizeof(char));
  printf("Size of char*: %d\n", sizeof(ptr));
  printf("Size of long: %d\n", sizeof(long));
  printf("Size of void*: %d\n", sizeof(void*));
  return;
}

AMD64 Results:

Size of int: 4
Size of char: 1
Size of char*: 8
Size of long: 8
Size of void*: 8

Intel Results:

Size of int: 4
Size of char: 1
Size of char*: 4
Size of long: 4
Size of void*: 4

It looks like the difference between the 4 byte int
size and the 8 byte pointer sizes on the AMD based
machines is causing the problem.

Regards,
Norm

p.s. I believe that a couple of other modules (other
than items.c) are effected by this.
