* mswindows.c (set_sleep_mode): Remove argument and return value.
Call GetModuleHandle() instead of LoadLibrary()/FreeLibrary() for
kernel32.dll. Use typedef for function-pointer. Don't cast
l-value. Don't use dereference operator when calling through
function-pointer.
(ws_startup): Update call to set_sleep_mode().
(ws_cleanup): Remove call to set_sleep_mode().
2004-02-23 David Fritz <zeroxdf@att.net>
* http.c (http_loop): Ditto.
