Repeated calls to ./config.status results in the same output for me:
...
config.status: creating include/libmesh_config.h.tmp
config.status: include/libmesh_config.h.tmp is unchanged
config.status: executing include/libmesh_config.h commands
config.status: creating include/libmesh_config.h - prefix LIBMESH for
include/libmesh_config.h.tmp defines
config.status: include/libmesh_config.h is unchanged

Did you mean config.log? Looks like the same output of config.status
that I pasted above is in config.log as well.
Note that just running 'make install' repeatedly, even without
touching any files, updates the timestamp on the libmesh_config.h file
_every_ time on my linux box.
Another file that seems to get updated every time is
${LIBMESH_DIR}/bin/libmesh-config, but it's pretty easy to see why...
we do some sed magic on it and then manually move it to its final
location rather than /usr/bin/install'ing it:
cat /home/petejw/projects/libmesh_git/install/bin/libmesh-config |
/bin/sed "s/has_been_installed=no/has_been_installed=yes/g" >
/home/petejw/projects/libmesh_git/install/bin/libmesh-config.installed
mv /home/petejw/projects/libmesh_git/install/bin/libmesh-config.installed
/home/petejw/projects/libmesh_git/install/bin/libmesh-config && chmod
+x /home/petejw/projects/libmesh_git/install/bin/libmesh-config
But I don't think we're doing anything like that to libmesh_config.h.
In fact I can see the command that installs it:
/usr/bin/install -C -m 644 libmesh/libmesh_config.h (... bunch of
other files ...)
'/home/petejw/projects/libmesh_git/install/include/libmesh'
and that should really do the right thing.
