error in distcheck caused by Info files modification time

[Marco Maggi]

Ciao,

  I use the Autotools in several packages with no problems running "make
distcheck",  but  in a  single  package  I get  an  error.   I am  on  a
x86_64-unknown-linux-gnu  with Autoconf  2.69 and  Automake 1.14,  and I
use:

   AM_INIT_AUTOMAKE([foreign dist-xz no-dist-gzip])

  AFAICT with  almost all of  my packages: when running  "distcheck" the
documentation is  built only in  PDF format,  not Info format;  the Info
files are already present in the distribution archive.

  In a single package[1] I get:

Making all in doc

`/home/marco/src/devel/scheme/vicare-scheme/=build.devel/vicare-scheme-0.3d5/_build/doc'

rm -rf $backupdir && mkdir $backupdir && \

then \
  rc=0; \
  CDPATH="${ZSH_VERSION+.}:" && cd ../../doc; \
else \
  rc=$?; \
  CDPATH="${ZSH_VERSION+.}:" && cd ../../doc && \
  $restore $backupdir/* `echo "./../../doc/vicare-scheme.info" | sed 
's|[^/]*$||'`; \
fi; \
rm -rf $backupdir; exit $rc

make[3]: Leaving directory 
`/home/marco/src/devel/scheme/vicare-scheme/=build.devel/vicare-scheme-0.3d5/_build/doc'

the problem seems  to be that the  Info files from the  dist archive are
extracted  with last  modification time  older than  their corresponding
Texinfo files  from the dist archive;  this causes the Info  files to be
rebuilt, which fails because the "doc" directory has permissions 0550.

  This happens also when I make sure to remove all the Info files in the
original build tree  and rebuild them, so that I  can verify[2] that the
Info files are newer.  It was not happening on this very package until I
split the documentation to 3 master  files, rather than an all inclusive
one.

  Was I just  lucky not to be hit  by this before?  I would  like not to
use the "info-in-builddir" option.

TIA
