.texi.html: Add a touch?

[Akim Demaille]

makeinfo does not update timestamps of directories:


% ls -dltr maintain.{texi,html}              nostromo 15:12
drwxr-xr-x    2 akim     lrde         4096 2004-05-25 14:38 maintain.html/
-rw-r--r--    1 akim     lrde        16132 2004-05-25 15:01 maintain.texi
% LC_ALL=C /bin/sh /home/akim/lectures/maintain/config/missing --run makeinfo 
--html --enable-encoding --number-sections --fill-column=76  -I . \
>  -o maintain.html maintain.texi
% ls -dltr maintain.{texi,html}
drwxr-xr-x    2 akim     lrde         4096 2004-05-25 14:38 maintain.html/      
-rw-r--r--    1 akim     lrde        16132 2004-05-25 15:01 maintain.texi


which keeps this rule unsatisfied:

.texi.html:
        $(MAKEINFOHTML) $(AM_MAKEINFOHTMLFLAGS) $(MAKEINFOFLAGS) -I $(srcdir) \
         -o $@ $<
        if test ! -d $@ && test -d $(@:.html=); then \
          mv $(@:.html=) $@; else :; fi


This can cause bad problems when trying to install under a different
identity:

% sudo -u doc make install                   nostromo 15:06
LC_ALL=C /bin/sh /home/akim/lectures/maintain/config/missing --run makeinfo 
--html --enable-encoding --number-sections --fill-column=76  -I . \
 -o maintain.html maintain.texi
/home/akim/lectures/maintain/maintain.html/index.html: Permission denied
make: *** [maintain.html] Erreur 1


so I suggest the following change:

from  Akim Demaille  <address@hidden>

        * lib/am/texibuild.am (.texi.html): Touch the output to update its
        timestamp, which is not performed by makeinfo when producing a
        directory.
