Building Make out of Git: Gettext requirements

[Eli Zaretskii]

Trying to build the current git head, I get this:

  $ autoreconf -i
  autopoint: *** The AM_GNU_GETTEXT_VERSION declaration in your configure.ac
           file requires the infrastructure from gettext-0.18.1 but this version
               is older. Please upgrade to gettext-0.18.1 or newer.
  autopoint: *** Stop.
  autoreconf: autopoint failed with exit status: 1

I have gettext-0.17 on this machine.

Do we really need to require 0.18.1 or can this restriction be lifted?
I hacked configure.ac to require 0.17, and didn't see any problems
afterwards.

(I hate it when each package I build insists that I upgrade to the
latest and the greatest of each of its dependencies.  When I build a
package, I don't necessarily intend to upgrade my entire system as
part of that build; in particular, I might have very good reasons for
sticking with older versions.  Sorry about the rant...)
