" This patch updates the events.c, filectl.c, gaiminc.c,
and mailchk.c plugins to the new api as well as
updating mailchk.c to the new buddy list code.

events.so, gaiminc.so, and mailchk.so all load and
function properly on my computer.

filectl doesn't even compile, but then, it has been a
while since it did actually compile. I didn't even bother
to update a few of the other plugins, since they're
completely out of date. Perhaps one of the developers
needs to go through and prune out a bunch of the
plugins that are not kept up to date.

Out of date plugins:

chatlist.c - superceded by faceprint's recent commit to
cvs.
filectl.c - doesn't support multiple accounts for IMs and
away messages.
raw.c - does anyone use this? it doesn't compile, but it
looks like an easy fix. "

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");

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)
