head requires gettext 0.16

[Eric Blake]

Head requires automake 1.10a, but Bruno said that gettext 0.15 is incompatible 
with automake 1.10.  So head now requires gettext 0.16, released today.  
HACKING is for CVS use only, so it is not mentioned in the Changelog.

2006-10-27  Eric Blake  <address@hidden>

        * bootstrap (gnulib): No longer a need to patch after gnulib-tool
        --update.
        * configure.ac (AM_GNU_GETTEXT_VERSION): Bump requirement to
        0.16, since 0.15 is incompatible with our automake requirement.
