It turns out that this doesn't actually work, and I can't find a
workaround. In Bash and Solaris's /bin/sh this executes until "dies
here". The problem is that I can't use the subshell trick, since the
gettext.sh inclusion has to be done in the current shell (I checked,
tests will fail).

    #!/bin/sh
    (. does-not-exist.sh)
    echo "A subshell made it! ret = $?"
    . does-not-exist.sh
  # dies here
    echo "A real shell made it! ret = $?"

Is there some clever shellscript trick that I'm missing, or will I
have to resort to modifying the file at `make' time for this to work
everywhere?

Works for me in bash (4.0.35), but fails the way you say in dash (if
only I could figure out the option that tells me the version!).

This works however:

 type does-not-exist.sh 2>/dev/null && . does-not-exist.sh

Thanks. That works, I've tested the following script:

    #!/bin/sh
    type meh.sh >/dev/null 2>&1 && . meh.sh && echo "Included meh.sh"
|| echo "Didn't include meh.sh"
    echo "I've made it!"
    type gettext.sh >/dev/null 2>&1 && . gettext.sh && echo "Included
gettext.sh" || echo "Didn't include gettext.sh"
    echo "I've made it!"

On the following:

    FreeBSD: /bin/sh, bash
    Solaris: /bin/sh, /usr/bin/ksh, bash,
    Debian: dash, bash

They all make it to the last "I've made it!".

I suspect it only works if the script is executable, as otherwise type
would not find it (but . would).  But at least on my system, it is.

With gettext.sh the assumption that it's +x seems valid, the
installation script for GNU gettext always gives it an executable bit.
