Looking at the code, I think you're wrong - it just autodetect.  Or at
least the code autodetect and contain ifdef's on ENABLE_NLS to
enable/disable code sections based on whether NLS is available or not.


For the more general case: I think we can use a dummy gettext library to
get around things needing gettext.  The gettext calls generally index on
the english string, making a dummy implementation very easy.

Below is an implementation (not tested) which should compliant with the basic
interface, and hopefully work.  A better variant might be actually have
all of this defined as inline functions in a header.

The docs I've found are at
    http://www.scit.wlv.ac.uk/cgi-bin/mansec?3C+gettext
and
    http://www.gnu.org/software/gettext/manual/html_node/gettext_145.html#SEC145
