Missing argz_add and argz_count in gnulb's argz.c

[Juan Manuel Guerrero]

Compiling CVS head checked out today with DJGPP gives the following output:

As can be seen argz_add and argz_count are not available.  This is a gnulib 
issue.
The function set defined in /gnulib/lib/argz.c does not provide the complete
function set that is used by texinfo.  It is clear that this issue must be
resolved by the gnulib maintainers.
