[PATCH] unsetenv: relax to LGPLv2+
Especially since setenv is also LGPLv2+, and it makes sense for the two modules to stay in sync. Signed-off-by: Eric Blake --- Libvirt wants LGPLv2+ when it uses gnulib, and recently ran into a problem where it can use the setenv module for mingw but not the unsetenv module. Barring any negative reviews, I'll push this in 24 hours, or sooner if I get a positive review; then libvirt will have to pick up the latest gnulib to make use of it. modules/unsetenv | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/modules/unsetenv b/modules/unsetenv index 015ac4e..909cec9 100644 --- a/modules/unsetenv +++ b/modules/unsetenv @@ -24,7 +24,7 @@ Include: License: -LGPL +LGPLv2+ Maintainer: all -- 2.5.5

These instructions download several 100's of MB of a git repository
and I wasn't willing to let it finish. I tried the file
"emacs-lisp-intro.texi" from
http://git.savannah.gnu.org/cgit/emacs.git/tree/doc/lispintro, and
after editing the file a bit (so it didn't need other files), I
processed it with that version of texinfo.tex. Unfortunately, I wasn't
able to reproduce the error. I did find one problem, though: some
entries in the tables of contents, like 13.1, have "{No value for
``COUNT-WORDS''} " instead of the proper value. That's likely been
brought in by the same change, and needs to be fixed. The change was
to expand @value when the table of contents file was read in, and not
when it was written out: however, in this file the @value is only
given a value (with @set) after the @insertcopying command. I
understand that this should work. I'll have a look at it. If I
remember correctly, I made this change in the first place to prevent a
similar infinite recursion error happening when writing an undefined
@value to an auxiliary file.

OK, here's a smaller example taken from the Emacs source code. Unpack
the attached tarball in a fresh directory, copy the latest Gnulib
texinfo.tex into it, and run the shell command 'texi2pdf bovine.texi'.
On my platform (Fedora 23 x86-64, texi2pdf (GNU Texinfo 6.0) 6363) the
output says './bovine.toc:1: TeX capacity exceeded, sorry [input stack
size=5000].' Full output log attached.
Thanks for looking into the problem.

OK, I got the same problem with the files you sent. I've committed and uploaded a new version that reverses the change, so @value is expanded at the time of writing again. Undefined @value's, when used in index entries, should not cause failures, either. It's quite possible that there is some combination that breaks, but it seems to work better for the files I tried.

Thanks, I verified that the new texinfo.tex works for GNU Emacs master 'make pdf', and installed it there.
