That template can be used for creating code that uses getopt() and/or
getopt_long().
However, to do that, that template must compile and run a small program.
I have added some clarification to its documentation:

Also, I seem to have lost the email I was looking at earlier.
Someone sent me a "test3.zip" file and a patch to alter gettext.tpl.
It has completely disappeared. No trace anywhere.
Anyway, the mod essentially added an extra layer of evaluation of CFLAGS
so that some extra quoting got stripped off of a command line
define for an include file name. I cannot exactly do that.
I'd recommend sedding a wrapper header that you always include instead.
e.g.:
sed 's/@@MARKER@@/$(FILE_NAME)/' test-wrap.h.in > test-wrap.h ; \
autogen -T getopt.tpl test.def
where the compilation of test.c needs to include $(FILE_NAME).
That will simplify all the layers of quoting required by the shell
and autogen and the C compiler. It gets confusing, but I think I
chased it to that cause.
