* gnus-start.el (): Added defvar statements to resolve compilation
warnings.
(gnus-long-file-names): New function. Isolates platform dependent
msdos-long-file-names.
(gnus-save-startup-file-via-temp-buffer): New variable. Provides
option of writing directly to file. Avoids memory exhausted
errors when .newsrc.eld is huge.
(gnus-save-newsrc-file): Uses new
gnus-save-startup-file-via-temp-buffer.
(gnus-gnus-to-quick-newsrc-format): Rewritten to write to
standard-output.
(gnus-display-time-event-handler): Changed to alias from a defun
to avoid a compile-time warning when display-time-event-handler is
not defined.
