Currently "make install" compresses the installed .el files depending
on the availability of the gzip program. In Gentoo we make this
compression configurable; with modern disk sizes the additional
disk footprint of 34 MiB is normally not an issue.
Since a long time Gentoo uses the following nasty hack for this:
<http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/app-editors/emacs/emacs-24.3-r2.ebuild?revision=1.15&view=markup#l98>
However, it would be much cleaner if the upstream build system
would allow to disable compression. The patch below adds a
--without-compress-lisp option for this. I've tested it on an
x86_64-pc-linux-gnu system and it works fine for me.

What's wrong with
GZIP_PROG='' make install ...
? This way, you don't need to decide up front whether you will or
will not want to compress, you decide at "make install" time.
If you want to disable compression of Lisp files, but leave alone the
compression of Info files, then I think it is much better to introduce
GZIP_LISP in the top-level Makefile.in without adding anything to the
configure script. Again, the advantage is that no decision need be
made at configure time.

That it doesn't work. ;-) Assignment in the Makefile overrides the
environment. ("make GZIP_PROG='' install" might work, though.)

I don't understand what would be the advantage of delaying the
decision. What additional information does the user have at install
time that he didn't have at configure time, and that would therefore
assist him with the decision? configure has the additional advantage
that things are remembered in the config.status file and in Emacs'
system-configuration-options variable, so you can recreate an
identical configuration from that.
Also, "configure --help" lists what options are available. But how
would the user discover that there is a GZIP_PROG variable? By reading
the Makefile? GZIP_PROG is at around line 260, not easy to find.

Having a configure option wouldn't prevent that. You can always
override the configure setting by passing a different setting of the
variable to "make install".

I see at least 2:
1) The default is always the same, no matter how the package was
configured. IOW, no need to remember or even care about the
options passed to the configure script, in order to know what will
happen by default with compression.
2) Not introducing yet another obscure option to configure, which
already has too many of them.

Perhaps you never produced more than one installation from the same
source tree. I do it all the time: sometimes I install on the same
machine, sometimes for copying the installation to another. The
end-user system frequently needs different options, because the needs
of the end users are different.

What do you mean by "recreate an identical configuration"?
> Also, "configure --help" lists what options are available.
Yes, all 75 of them.

Those few that care will find it out once, and then remember it, like
they remember this new option to configure.

Too many? Emacs is a complex program, so of course it has a number of
configure options. They all come with a default, so the user only must
specify them if he wants something that differs from it. Isn't it one
of the principles of GNU that "a user who needs changes in the system
will always be free to make them himself"?

Really, there's no need to tell a distro maintainer about different
needs of users. ;-)

Sorry. But then I don't understand how come you don't realize the
advantages of a single build tree that can be installed in umpteen
different ways.

As I said before, adding a configure option in addition wouldn't
prevent this.
But I think that I've put my arguments forward. So either accept my
patch, or close this bug as invalid if you don't like it. In the
latter case, you should presumably remove the --without-compress-info
option, for consistency.

I simply renamed and generalized --without-compress-info (which exists,
BTW, because "I do not know if all info/man support compressed files,
nor how to test if they do so") to --without-compress-install.
Anyone who wants some things compressed during install and some things
not is on their own.
