* ./configure.in: we now require autoconf 2.5x because previous versions
don't seem to work very well if you are using autopoint, although
gettext 0.11.5 claims to be fully backwards compatible. Welcome to
automake hell.
* ./bootstrap: workaround which uses gettextize if you do not have
autopoint. We'll probably stay like this for a while, until gettext
0.11.x (which replaces gettextize with autopoint) becomes more
widespread. Currently this workaround seems to work, but don't expect
a clean tarball if you make dist without having used autopoint. Welcome
to automake hell.
