Re: unconditional inclusion of argz.h; missing declared functions in argz.h

[Karl Berry]

    No it does not really work.  As can be seen, now the configure
    script checks for argz.h and declared functions and detects that
    they are not available but it has no concequences.

Well, apparently there is a difference: it is finding <argz.h> now since
it didn't complain about that -- argz.h was presumably generated under
the gnulib/ subdir since it wasn't on the system.

Unfortunately I do not know why the gnulib/lib/argz.c file which defines
all those symbols did not also get compiled, thus making the link fail.
Can you (or anyone) try to debug that?

Then apparently there is an independent problem of asprintf being
missing.  I'll rewrite the code to avoid using that.

Thanks,
