" An update to com_err on debian appears to have broken
the ability of the zephyr plugin to compile with krb4.

Here's a patch, tested against comerr-dev
2.1-1.34+1.35-WIP-2004.01.31-1 in debian, and an older
version of com_err local to MIT, that fixes this. I
haven't tested this against non-kerberized zephyr, or
against other versions of com_err. A lot of the comerr
(error table) related code appears to be unnecessary.

This also fixes two other issues:
1) Upon each login, every entry in the "Anyone" group
was getting added to the Buddies group. I didn't notice
this earlier, since I usually don't restart gaim very
often.

2) No more compile warnings.

This also replaces occurrences of ZGetSender and
ZGetRealm with gaim_zephyr_get_sender and
gaim_zephyr_get_realm(),
in preparation for getting gaim to alternately use an
external program, "tzc" to talk to zephyr."

Notes on keeping GAIM OS independant
------------------------------------

General
-------
- Use G_DIR_SEPARATOR_S and G_DIR_SEPARATOR for paths

- Use g_getenv, g_snprintf, g_vsnprintf

- Use gaim_home_dir instead of g_get_home_dir or g_getenv("HOME")

- Make sure when including win32dep.h that it is the last header to
  be included.

- Open binary files when reading or writing with 'b' mode.

  e.g: fopen("somefile", "wb");

  Not doing so will open files in windows using defaut translation mode. 
  i.e. newline -> <CR><LF>

Paths
-----

- DATADIR, LOCALEDIR & LIBDIR are defined in wingaim as functions.
  Doing the following will therefore break the windows build:

  printf("File in DATADIR is: %s\n", DATADIR G_DIR_SEPARATOR_S "pic.png");

  it should be:

  printf("File in DATADIR is: %s%s%s\n", DATADIR, G_DIR_SEPARATOR_S, "pic.png");

- When writing out paths to .gaimrc, use wgaim_escape_dirsep. This is necessary
  because the Windows dir separator '\' is being used to escape characters, when
  paths are read in from the .gaimrc file.

PLUGINS & PROTOS
----------------

- G_MODULE_EXPORT all functions which are to be accessed from outside the
  scope of its "dll" or "so". (E.G. gaim_plugin_init)

- G_MODULE_IMPORT all global variables which are located outside your
  dynamic library. (E.G. connections)

  (Not doing this will cause "Memory Access Violations" in Win32)
