Yes, we should start using AM_GNU_GETTEXT instead if intl is removed.

The biggest pain I see in zlib is more aesthetic than anything else; 
we'd need to disable libjava if it is not there, and this means that 
we'd add one more test to the toplevel.  Such tests really belong in the 
front-end directories.
