Isn't this funny?
NNTPSERVER=flab; export NNTPSERVER
emacs -batch -Q -eval '(message "%s" (getenv "NNTPSERVER"))'
=> flab
emacs -batch -Q -eval '(message "%s" (gnus-getenv-nntpserver))'
=> flab
emacs -batch -Q -eval '(message "%s" gnus-select-method)'
=> nil
In Emacs, `gnus-getenv-nntpserver' and `gnus-select-method' are
defined in loaddefs.el but it is not loaded when Emacs starts.
I guess the nil value of `gnus-select-method' was set at the
time when I built Emacs. It suggests that the default value of
`gnus-select-method' is decided according to the Linux
distributions, without minding what is suitable to a user. I
don't have an idea to fix this except for removing the autoload
cookie.
Regards,
P.S. XEmacs complains as follows when compiling this autoload:
Compiling gnus/lisp/auto-autoloads.el...
While compiling toplevel forms in file gnus/lisp/auto-autoloads.el:
** reference to free variable gnus-default-nntp-server
** reference to free variable gnus-nntp-service
Wrote gnus/lisp/auto-autoloads.elc

I always have set NNTPSERVER set, both when building and running Emacs
and I get the same results.

Isn't loaddefs.el dumped into the binary?

This is not true according to my observation.

The idea of the autoload for `gnus-select-method' was to make `M-x
customize-variable RET gnus-select-method RET' work without starting
or even loading Gnus. But maybe my change was incorrect, cf. Nelson
Ferreira's report for XEmacs:
<http://thread.gmane.org/gmane.emacs.gnus.general/63964>.
Here a different approach:

I always have not set env vars if there are alternative Lisp
variables that can be set in .emacs file. But now I realized
the reason `gnus-select-method' defaults to nil is not related
to the value of NNTPSERVER.

Yes, I verified it. The default value of `gnus-select-method'
is always nil. I stripped two `condition-case' from the
`gnus-select-method' form in loaddefs.el, removed src/emacs, did
`make', and got the following error:
LC_ALL=C ./temacs -batch -l loadup dump
[...]
Loading loaddefs.el (source)...

I see. But the present way restrains the intention of the value
form in defcustom, that is, attempting to set a default value
suitable to a user according to NNTPSERVER.

I tried it and felt that's much better. It doesn't bound
`gnus-select-method' at the startup but enables a user to do
`customize-variable' without loading Gnus. Moreover, it offers
a default value which reflects the value of NNTPSERVER.

`custom-autoload' is not available in Emacs 21 and XEmacs 21.4.
I'll look for another way...

Er, that might be a stupid talk. `(fboundp 'custom-autoload)'
means that we don't need to mind even if those who use old Emacs
cannot do `customize-variable' before loading Gnus, doesn't it?
If so, could you commit the new autoload?
In addition to this, it seems good to add `custom-autoload' to
lpath.el to silence old Emacsen:

Yes. It would be nice if there's a possibility to make it work for
Emacs 21 and XEmacs 21.4 as well.

Done.

Added.
