Hello,
FWIW, I've put Karl and Vincent back in Cc:.

At least both older and newer Automake and gettext versions would need
to be checked. (I'm not saying the change shouldn't be made, at least
one could consider the possibilities of setting it to
'${SHELL}'" $ac_install_sh"
'$(SHELL)'" $ac_install_sh"
"$SHELL $ac_install_sh"

That won't work for read-only source trees. Of course, at the first
time configure is run, a read-only source tree may even break in other
places, but I'd hate to add more instances like that. At the least, the
bogus error output of chmod's failure should be suppressed.
(Hmm, do people mount CDs with no-exec flag? Then using a shell prefix
in some way or other can't be avoided IIRC.)
Karl, for texinfo, why do you even store install-sh in CVS (and why was
it added there without execute permission)?
Cheers,
Ralf
