* fhandler.cc (fhandler_base::set_no_inheritance): Always use
SetHandleInformation. * fhandler_disk_file.cc (fhandler_disk_file::lock): Always use UnlockFileEx/LockFileEx functions. * net.cc (fdsock): Don't bother to duplicate socket for inheritance. * sysconf.cc (get_nproc_values): Take NT for granted. (get_avphys): Ditto. * syslog.cc (WIN95_EVENT_LOG_PATH): Remove define. (get_win95_event_log_path): Remove. (vsyslog): Fix formatting. Take NT for granted. * wincap.cc: Remove has_lock_file_ex, has_signal_object_and_wait, has_eventlog, has_set_handle_information, has_set_handle_information_on_console_handles and supports_smp throughout. * wincap.h: Ditto.
